Hi,
To upgrade from 14.3 MP1 (embedded database) to RU1 MP1 (SQL express database) i first installed a new SEPM server (server "B") with 14.3 MP1 (embedded database) as replication site.
Then i changed communication policies to force clients to communicate with the new server "B".
When all clients connected to new server "B" i upgraded the new server "B" from 14.3 MP1 to RU1 MP1 (SQL Express database).
Then i uninstalled SEPM 14.3 MP1 from the first server "A" et ran Symantec CleanWipe to clean server "A".
So i am trying to make a fresh install of SEPM 14.3 RU1 MP1 and server "A" but i get "failed to upgrade database certificate".
Thanks for your help
