Pre-upgrade check failure during vCenter Server 5.5.x upgrade (2144262)

  • 2 Ratings


Upgrading vCenter Server from 5.5 Update 3 to 6.0 Update 2 fails during the pre-upgrade check.
The failure is seen when you use SQL 2012 or 2014 AAG setup.


Perform the following steps to configure the database to meet the vCenter Server upgrade requirements on Windows:

  1. On the vCenter Server machine, update the ODBC Data source Name (DSN) with Standalone Database IP address.
    Note: The ODBC DSN points to the listener IP address.
  2. On the primary node database machine, remove the database details from AAG configuration.
  3. Upgrade the vCenter Server to 6.0 Update 2.
  4. On the primary node database machine, take a back up of the database.
  5. To avoid conflict, delete the database with the same name from the secondary node.
  6. Add the database to the AAG configuration.
