...
Settings

Mappings
...
Defaults
The Defaults tab defines the default settings that are displayed on the migration initiation screen.
...
Customer Prefix defines the prefix for multiple dialplan objects deployed for Template Migration only
Site Prefix defines the prefix for multiple dialplan objects deployed for Template Migration only
...
Mapping Object Defaults
The Mapping Object Default Matrix defines source data objects mapping to target data objects. These should be left as default
...
Mapping Tables
Mapping Tables contain Templates that are used to determine Sites during the Site allocation migration step. These regexes can be modified as required to correctly match source cluster settings required to create site suggestions during the migration. Note that these are global settings, but they can also be modified on a migration specific basis during the migration. This is described under migration process chapter.
...
Tip - most Mapping Table common object used to create site suggestions is Device Pool, but the more objects are mapped the easier it is to determine migration object site allocation
Source Type Actions
Depending on the dial plan migration option the CUCM configuration objects will be migrated using one of the four functions.
...
Tip - If unsure what objects requires mapping (needs preconfiguration in target) the Source Type Action Defaults table will confirm all objects that require mapping for each dialplan migration type
Site Suggestions
Site Suggestion work in conjunction with Mapping Tables to define specific conditions to be met for creating sites. In example as per screen shot below, it is specified that Device Pools are mandatory for site suggestions and that there needs to be a minimum of 1 template match to create a site suggestion.
...
Tip - most common object used to create site suggestions are Device Pools
Schemas
...
Schemas contain templates defining how objects are treated during a migration. The initial installation contain a Default schema, but customised schemas might be imported and used if required.
...
| Note |
|---|
The Default schemas should not be altered - if for some reason changes are required, the default schema should be cloned and modifications performed on the clone only |
Customer
The Customer Screen display enables information regarding the customer to be added and modified as and if required in the Override Value column, then Save Changes
...
Clusters
The source and target clusters are automatically defined after discovery for single source and target cluster migration.
The Clusters menu item displays information regarding the Source and Target Cluster interfaces and servers
...
Selecting the MainTargetCluster link displays information re the target cluster.
It is not recommended to change any value in the Cluster or other tabs here unless advised to by support
...
WxC-MT
Licenses
A default license must be defined for WxC-MT migration. The Licenses menu option displays defined default licenses for the current migration, and allows for the addition of new or removal of previously defined default licenses.
...
To remove displayed license/s - select the X in red box adjacent to the license
...
Roles
The Roles menu option allows for the addition of required/ removal of previously defined WxC-MT Roles for the migration by selecting Roles to be added from the drop down followed by the +Add button and/or the removal of previously defined Roles for migration by selecting the X in Red Box
...
Sites
Sites are used to group the various configuration objects within the source cluster and are also selected for the migration batches
...
Site may also be Imported and Exported in CSV format for bulk updates of details, this is particularly useful when many sites for Grouping sites and also for adding Address details that are required for WxC-MT migrations as can be seen in below screenshot
...
Countries
The Countries menu option allows for the view, add or modification of country details pertinent to countries where migrating sites resides. These settings are used for site country allocation
...
Select the country from the Identifier column to view and edit country specific details
...
Mapping Tables
The Mapping Table option within the migration allows for the change of mappings on a per migration basis, then preview to check if the defined templates generate site suggestions as required. To check site suggestions for a particular mapping table option - select Preview table adjacent to required mapping source - in the below sample, we select Preview Table adjacent to Device Pools, although any of the Objects in the Name column can be used to generate sites.
...
If we now add a new template to try and match the DP that was not matched in original run, then Save and Preview, we can now see that the Device Pools match the new template.
...
Target Mappings WxC-DI
Select Target Mappings menu item to view the status of all objects. The Target Mappings are divided into four object types:
...
You can view the details of each object for each type.
Map Types
Map types are objects that must be mapped from source to target clustter. The types show objects in Unmapped, Mapped, Skipped, Loaded state. During a migration you will be prompted to map the objects that are currently unmapped, all of these are highlighted in Yellow in Map Types (mandatory mappings) section under Source Cluster Objects, Unmapped, Customer headings and cannot progress until all mappings performed.
...
If there are objects that should not be migrated, from the target object drop down, select Skip Target Binding
...
Transform Types (only shows in Map or Template Migrations)
Transform Types are objects that are transformed during a Map or Template migration where the object needs to be transformed such as for example if a partition changes between source and target, all the objects that use that partition will be transformed to use the new target partition
As per the Map types, the Transform Types shows the migration status summary of all transform objects, Waiting, Transformed, Skipped and Moved state.
...
Clone Types
Clone Types are objects that are cloned from source to target
...
| Note |
|---|
Note that renaming of objects such as device pool is not fully automated for clone and is not recommended If you do rename device pools it should be done during clone on the cloned object but you will need to update every reference for the object i.e. for device pool each phone that references will need to be updated with the new name |
Skip Types
Skip types are objects that are skipped in the migration
...
Objects can also be set to skip using bulk change from v2.5.15 by setting the targetId to Skip
...
Target Mappings WxC-MT
Select Target Mappings menu item to view the status of all objects in a WxC-MT migration. The Target Mappings are here divided into:
Mappings
Multi-Tenant Transforms
Skipped Types
Skipped Objects
Mappings
Mappings are objects that must be mapped from source to target. The types show objects in Waiting, Skipped, Issues and Mapped state. During a migration you will be prompted to map the objects that are currently unmapped, all of these are highlighted in Yellow in Mappings section and cannot progress until all mappings performed.
Multi-Tenant Transforms
These shows the status of objects that are transforming from CUCM format to WxC-MT format
Skipped Types
These how types of objects that don’t have any mappings in the particular migration
Skipped Objects
Shows specific objects with no target mappings in the migration
Schema
Templates

Here the template can be modified and a preview on the outcome of template be performed by selecting the Preview Template Button to verify the expected outcome prior to migration or for troubleshooting.
