WRANGLER

Login to Wrangler Application. Select New Customer Migration

WRANGLER

Define Source and Target UCMC Interfaces as defined earlier, Optionally define Initial countries (countries covered by Source CUCM

Select Dialplan Configuration ‘Clone – Clone Source Dial plan’, then ‘Save Migration $ Start Discovery’ to kick off the migration

WRANGLER

On Completion of Initial Discovery/ Allocation/ Validation we need to define Sites, and resolve any issues

WRANGLER

Select ‘Site Suggestion’ tab to define Sites. Mappings created previously for Device Pool and, if required other objects, should ensure that Sites suggestion displayed match these*. Select ‘Create Site’ for each site, or select all under ‘Bulk Action’

• If expected sites (Device Pools) not showing, then additional mappings will/may be required as explained here

wrangler_ WxC-DI Migration User Guide | Site Allocation

WRANGLER

Select the Warnings Tab

Warnings tab displays issues from initial validation checks such as lines without phones, users without lines, users without emails etc. None of these issues will stop migration proceeding and may be disregarded by selecting ‘Disable Rule And Clear Issue’

Or if these issues/ some of them should be rectified prior to proceeding. Select the blue button adjacent to each object type flagged – this will display all the objects of that type with the highlighted issue.

These may then be exported and the issue rectified in source CUCM followed by Fast Re-Sync All option

WRANGLER

Select the ‘Issues & Resolutions’ tab

These issues must be attended to before progressing migration

Some issues and suggested solution to these are described below

For a list of all validation rules, what they mean and suggested solutions to them, they may be found here

Wrangler WxC Validation Rules and Solutions

IPCC + CRS in source but not in target

Solve by integrating CRS to target + Rediscovery or if not required, select ‘Disable Rule And Clear Issue’

Directory URI Partition in Enterprise Parameter not same in target

Solve by creating required partition and add it to the CUCM Enterprise Parameters in target, then Rediscover

Detected authenticated or encrypted Phone and SIP Trunk Security Profiles

If required in target, add security license to target + rediscover or if not required, ‘Disable Rule And Clear Issue’

There are LDAP integrated User in source not existing in target

Solve by Resyncing the target or select ‘Bulk Skip Users’ to skip users from migrating

Local User exist in source with an LDAP user in target with same mailid

Select ‘Bulk set mailid empty for local user’ to clear mailid for user or if this user

There are Device Pools that are not allocated to site

This issue may be ignored until after Reallocation performed as provided Mappings performed correctly this issue will disappear as part of Site Allocation

Orphaned Hunt Pilots

This is Hunt Pilots without Hunt List – to solve select ‘Skip Objects’

EM Profiles not allocated to site in source cluster

This issue may be ignored until after Reallocation performed as provided Mappings performed correctly this issue will disappear as part of Site Allocation

Deprecated devices in source

Solve by selecting ‘Skip Deprecated Devices For Migration’

Duplicates in Target with unique configuration

This flags that there are Duplicate objects in target but with different configuration to the source duplicate. To review the duplicate difference, select ‘Review Duplicates’ which will bring up links to the duplicates for review

If target is to be updated with configuration from the source duplicate object select ‘Update Target Object’ (this would generally be the selection that should be used and is always the action for LDAP integrated users) or ‘Ignore Source’ which will keep the Target object as is

Source Cluster has Custom Ranks

There are User Ranks with Rank >1 configured in source cluster. Configure corresponding User Ranks in Target, then Rediscover or ‘Disable Rule And Clear Issue’

Mapping

These objects must have been created in Target and source object then mapped to corresponding target (note that if source and target objects have same name, they will be mapped automatically). Select the ‘Manually Resolve Unmapped’ which will bring up the unmapped objects of the type, then map as required

Mapping process (and Issues & Resolutions) is further explained here wrangler_ WxC-DI Migration User Guide | Issues& Resolutions (below description and samples apply to single cluster migr...

When all validation rule issues cleared, select ‘Re-Allocate Migration’

WRANGLER

If after Reallocation, some issues still remain Resolve these, then Re-Validate until no further errors are detected

In sample migration

Sites with no Country defined

To solve these, ‘Select Country Code’ then from drop down add required country

Note: Bulk Change Option may be used if there are many issues flagged of same type. How to use Bulk Change option here Wrangler WxC Administration Guide | Bulk Changes

Once all issues cleared – ‘Re-Validate Migration’

Once All Issues and Resolutions and Site Allocation processed, continue with Prepare Sites Step

WRANGLER

Select Sites from menu to enable site migration batch

Select the Sites to migrate by Clicking on the ‘Waiting’ adjacent to site in the ‘Select’ column, or to select all sites in one go, Bulk Select may be used

Return to ‘Ready’

Next step is to select ‘Re-Validate Migration’

On Completion of Validation – ‘Preview Prepare’ then ‘Start Migration'

This will start the Cloning process, where all source objects are cloned in Wrangler, ready for Load Stage

Select ‘Continue Migration’ which will proceed migration to Load Sites Stage

Again Select ‘Re-Validate Migration’ to proceed with pre load stage validation.

Select ‘Issues & Resolutions’ tab to view any pre load validation issues

Sequencing Issues Rectification

Rectify any sequencing issues by selecting to move the flagged object to load stage ‘Before Any Sites Loaded’; or

move dependant Dependent objects ‘View x Dependant Object’ to ‘During Site Load’

Tip – generally better to Bulk Change Dependant objects to ‘During Site Load’ other than Region and Locations that can best be moved to ‘Before Any Sites Loaded’

Other issues that may be highlighted during the re load validation that may stop the objects from being loaded into the target are

Jabber Device Lines with Max Num Calls parameter set to >2

Solve by ‘Resolve With Bulk Change’ which will change all Jabber Device Lines with Max Num Calls >2 to Max Num Calls = 2

Users with Primary Line defined but no associated devices

Solve by ‘Bulk Remove Primary Line’ which will remove primary line from users with no associated devices

Phones with Primary Phone populated with own device

Solve by ‘Bulk remove Self Reference from Phone’

Device with pending certificate operation caused by devices unplugged/unreachable during a cert upgrade

Solve by ‘Set to “No Pending Operation”’

When all issues cleared – ‘Re-Validate Migration’

Some new sequencing issues may reappear – as per above clear these by moving objects to ‘Before Any Sites Loaded’ or Bulk Change dependencies to ‘During Site Load’ – again Re-Validate Migration’ Repeat this until all issues cleared

Tip: If there are many sequencing issues of the same type, Bulk Change may be used to change them to different Change point – ‘Before Any Sites Loaded’ or ‘During Site Load’ stages

For Example – if we wanted to change all Regions and Locations to change Point ‘Before Any Sites Loaded’

Navigate to Bulk Change, then ‘Create Bulk Change’

Select Objects to change in Filters , select Target Cluster, then ‘Search & Find Objects’

When objects show, select ‘Next’

Scroll down to Edit Overrides Header, ‘Set Allocated site’ to ‘Set to “null”’ and ‘Change At’ to ‘Before Any Sites Loaded’

Select ‘Review Bulk Changes’, then ‘Apply Bulk Changes’

More on Preload validation issues and Tip here Wrangler WxC Tips and Hints | Pre Load Validation Issues

When all preload issues are cleared – move to Load Sites

Start Load by selecting ‘Preview Load’, followed by ‘Start Migration’

This will load objects into target CUCM

WRANGLER

On completion of Load review any Errors by selecting Events Tab, then Errors

Error Details may be viewed by selecting the individual error. Within the error detail will be a link to open the object in Object Browser from where issue may be resolved by removing the issue causing the error or such

@Mats Age we can remove error details below here i think unless there is a reason?

In sample above CUCM-DEVICE-DEFAULTS causing error selecting highlighted link brings up object detail in Object Browser

We can see that issue is missing Phone Button Template – this particular issue is because it is Device Default for deprecated device type Cisco 7921. Issue can be fixed by Clearing the Phone Button Template Field then saving

Once all errors have been rectified – ‘Restart Execution Process’, then migration complete
