Upgrade from DA90SP4 to DA10SP4CHF1 breaks SQL replication
We had the below issue occur twice in different environments. This might or might not be happening to you, but if it does, you know now...
Windows 2008 R2 x64 standard edition (EV and SQL server). SQL 2008R2SP2 standard edition, with log-shipping as DR solution (replication). Enterprise Vault 9.0SP4, and DA9SP4
Upgrade DA9SP4 to DA10SP4 - upgrade config-database, upgrade customer-db, verify evbaadmin is ok, verify DA10SP4 client connects ok.
Apply CHF1 for DA10SP4 - upgrade etc. Verify DA10SP4CHF1 client connects ok.
Monitor SQL logshipping. You might see error:
The log shipping primary database PROD SQL SERVER\INSTANCE.xxxEVDACM has backup threshold of 60 minutes and has not performed a backup log operation for 61 minutes. Check agent log and logshipping monitor information.
