8.18.1 Start migration
* 
A running migration can take up to 30 minutes, depending on the size of the system. During this time the telephony functionality is not available to the customer.
To better plan the migration of desired UC Tenants, first check the list of migration tasks already entered for your Partner or Platform, see 8.18.2 Migration tasks.
 
* 
After successful migration, it is necessary to update the following settings on the customer side:
- The endpoint for the VPN must be updated in the configuration of the VPN Gateway in the local customer network.
The required information (VPN remote peer and identity of the VPN remote peer) can be found under UC Tenant | Network | Offices | | Information.

- Mobile clients and SwyxIt!/NetPhone clients must use the new Swyx RemoteConnector endpoint.
The corresponding endpoints can be found under UC Tenant | Network | RemoteConnector.

You can export the data required for the VPN configuration to a PDF file, see 8.25 Viewing gateway settings for Offices.
 
* 
The UC tenant remains on the current Scale Unit until a full copy is created on a target scale unit. In the event of a failed migration, telephony functionality is resumed and the migration can be rerun at a later time.
 
* 
During migration, you cannot edit the offices of the corresponding UC tenant.
 
* 
If the migration fails, you will be notified by email.
