Upgrades to RSSD or ERSSD and User Databases

After you upgrade the Replication Server RSSD or ERSSD, you must apply upgrades to a primary, replicate, or standby database in the replication system to accommodate changes, such as installing new stored procedures, that support the new version of Replication Server to which you are upgrading, and features such as Multi-Path Replication™.

Upgrading an RSSD or ERSSD may add new Replication Server system tables, add new rows or columns to existing tables, or install new stored procedures. To accommodate changes that support the new version of Replication Server to which you are upgrading, repserver or rs_init applies upgrades to user databases such as a primary, replicate, or standby database in the replication system.

If you do not apply the upgrades to replicate databases such as:

Adaptive Server – you cannot use Multi-Path Replication for replication to Adaptive Server databases after you upgrade Replication Server to 15.7 and later.
Sybase IQ – Replication Server suspends replicate connections to the Sybase IQ replicate databases after you upgrade Replication Server to 15.7.1 or later, and you see a "Awaiting Upgr" status if you use admin who. You can upgrade the Sybase IQ database using one of:
- repserver -upgr – upgrades Replication Server at the same time
- sysadmin upgrade,'database' – after upgrading Replication Server with rs_init or repserver with the -nodb option
