Upgrading from 
Good Control
 or 
Good Proxy
 to 
BlackBerry UEM

To upgrade 
Good Control
 version 4.0 and later or 
Good Proxy
 version 4.0 and later to 
BlackBerry UEM
 version 12.9 you must first upgrade 
Good Control
 and 
Good Proxy
 instances to 
BlackBerry UEM
 version 12.7 or 12.8 and synchronize the environment before the upgrade to 
BlackBerry UEM
 12.9. 
If your environment consists of 
BES12
 version 12.5 that is integrated with 
Good Control
, you must first upgrade to 
BlackBerry UEM
 version 12.7. Use the setup application to upgrade both 
BES12
 and 
Good Control
. Do not use the 
Good Control
 installer to upgrade 
Good Control
 in this scenario. For more information, see the 
Planning Guide
 and the 
Installation and Upgrade Guide
 for 
BlackBerry UEM
 version 12.7.
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.
