Warnings
The Warnings tab displays items that have triggered the rules but are information warnings only that may be attended to as required. Items that are highlighted under warnings can be missing e164 numbers, Intercom partitions and CSS's, Devices without Lines, Lines without Devices etc. If these require updating, select the blue button which will take you to the item in question. If no action is required for the individual item, the Red Button + Disable Rule and Clear Issue may be selected to clear the issue. When Warnings have been attended to, continue by selecting the Issues & Resolutions Tab
...
When all issues are resolved, select Re-Validate Migration

Tip: If you receive many errors for invalid numbers, you may need to add country to the site where errors are or default country not added. The default country may be added under Dialplan->Configuration- Numbers Tab. Individual site country can be added under Allocation->Sites, then select the relevant country from Country field, in override column + Save, then perform reallocation |
...
Prepare Sites stage
On resolving issues and revalidation successfully completed, the ‘three migration step’ screen is displayed. To progress from here, we now need to select what sites should migrate.
...
On completion of load, check for any errors during load by selecting the Events Tab and Errors box which will display the errors. Selecting the error will display the error detail and which object failed. In sample migration, 2 phone devices failed to load as they were duplicates of existing MAC addresses. To resolve - there will be a link within the error detail linking to object detail (can also be accessed using Object->Browse from menu then finding the detail of the offending object) where the error can be corrected and load process restarted by selecting Restart Execution Process
...
On rectification of issues and restart all objects loads OK

Advanced Features
Number mapping and Normalisation
...
This feature was added for WxC-MT migration to automatically normalise numbers - this can be reviewed in Discovered Numbers - Number Mappings
Supported infra source transformation
...
CUCM Directory Number
...
External Number Mask
...
External CLI will only be automatically populated if the CUCM-LINE pattern is in Full National Number (FNN) format and either the default country or site country is set
The infra-source will need to be updated to included the external CLI if there is asymetrical CLI - inbound number is different to outbound CLI if the CUCM-LINE pattern is an extension

Acronyms
Extn - Extension
FNN - Full National number

Normalisation using FNN requires that sites are created with the country set and re-allocation to be run |
Number mappings - Bulk Change
Added in wrangler_ 2.6.8
Bulk change was added to the number mappings view to enable bulk skipping / reset / force and map to existing number
This may be used if you need to clear the number mappings to infra-source if the countries were not correctly set initally or to force invalid FNN/e164 numbers that are used for non-DID services

Number mappings - Export Numbers
Added in wrangler_ 2.6.8
This provide an excel export of the number mapping view

once imported a report of the changes will be provided
Workspace Device Load
In wrangler 2.6.5, wrangler_ loaded Workspaces but not Workspace devices into Webex Calling Control Hub. A workspace is created for every CUCM phone device of valid phone device type with no owner UserId. This was resolved in 2.6.6
