Considerations for upgrades from 
BlackBerry UEM

If you are upgrading from a previous version of 
BlackBerry UEM
, make sure your servers meet the requirements for the 
BlackBerry UEM
 configuration you are upgrading to.
Each 
BlackBerry UEM
 domain you are upgrading must be synchronized before the upgrade.
If you have any inactive 
BlackBerry Connectivity Node
s, either activate them or remove them from the environment. If you do not activate them before upgrading, any devices they manage will be removed.
