10 Recovery Procedures
Upgrade procedure recovery issues should be directed to the Oracle's customer care. Before executing any of these procedures, refer to my-oracle-support-mos.html#GUID-AAD93B71-B4B8-4F1C-83E5-16C9C91CC52E__GUID-AAD93B71-B4B8-4F1C-83E5-16C9C91CC52E.
Recovery procedures are documented in the Disaster Recovery Guide. Run this section only if there is a problem and it is desired to revert back to the pre-upgrade version of the software.
Note:
Back out procedures cause traffic loss.Note:
These recovery procedures are provided for the back out of an upgrade only (for example, for the back out from a failed target release to the previously installed release). Back out of an initial installation is not supported.Note:
If the customer deployment has both the FABR and PCA features enabled, then upgrade the DSR nodes first before upgrading the SDS nodes.
