Issue

When upgrading from 4.7 to K2 5.3, if duplicate attributes LogLevel=Error;LogSize=0;LogLevel=Error;LogSize=0; are detected in the [RoleInit] column for the K2 SecurityLabel:

The upgrade would fail with the following error:

Symptoms

Although you can update the K2 Security Label, and remove the duplicate "LogLevel=Error;LogSize=0;" entry from the [RoleInit] column and then successfully re-"Configure" K2 Five.  The installation of the 5.3 New Identity Service Opt-in would be successful.  However, performing the initial sync results in an error:

0 Execute 'RunSyncJob' Error : The Provider Instance with Name or ID 'DENALLIX' was not found.

The applicable entries were not seeded into the [SyncEngine] tables resulting in the error.

Resolution

1.  If a 4.7 K2 database backup and 4.7 K2 server VM snapshot exists prior to the upgrade:

  1. Revert to the 4.7 snapshot
  2. Restore the 4.7 K2 database backup
  3. Remove the duplicate LogLevel=Error;LogSize=0; entry
  4. Re-perform the upgrade

2.  If a 4.7 VM snapshot does not exist

  1. Uninstall K2 Five
  2. Restore the 4.7 K2 database backup 
  3. Remove the duplicate LogLevel=Error;LogSize=0; entry
  4. Re-install 4.7
  5. Re-perform the upgrade

3.  If neither exists, logging a Support ticket may be necessary.
