# Template Migration

When you upgrade from a previous release, the templates in the database restore are updated with any new fields. Generally, any new fields introduced in the release are either blank or set to an appropriate default.

Note: All phones created in MiCollab Release 4.0 and earlier are full service phones. Therefore, any templates that are migrated to Release 5.0 or later will have a service level of Full. If you want to assign users with PRGs or MDUGs, you must modify the service level of the phone on the MiVoice Business .
