How to run post-upgrade for on-premises instances when there are multiple servers

Description description


  • Campaign Classic

If there are multiple servers both having web@default running, should the command be run on just one of the servers or both?

Resolution resolution

  • If you happen to have multiple ``< instance> .conf files in the same box, and each one has a distinct connection to different databases (usually seen in environments with complex failover config), then you will have to upgrade the structure of two databases.
  • If you have multiple ``< instance> .conf files pointing to the same database in the same box, then there is no point in running allinstances param. When all servers are connected to the same database, running the post-upgrade on the primary server is sufficient, and using the allinstances param will do just fine.

Note: If you want more control on what’s being upgraded, it is better to explicitly define the instance to upgrade.
