Chapter 7 Backing Up and Restoring the GSSM
Downgrading Your GSS Devices
Downgrading Your GSS Devices
If you encounter problems with a GSS software upgrade, restore an earlier version
of the GSS software on your GSSs and GSSMs. To restore an earlier version of
your software, you must have a previous backup of the primary GSSM database
that corresponds to the current version of GSS software. For example, if you wish
to downgrade from GSS software Release 1.2 to GSS software Release 1.1, you
must have a GSS software Release 1.1 database backup that you can restore. Your
GSS software Release 1.2 database cannot run on the Release 1.1 platform
because of changes in the database schema between releases.
When downgrading the GSS software, use the following order of operations to
safeguard your critical GSS data and properly restore your GSSM database:
1. Verify the GSSM role in the GSS network
2. Perform a backup of your primary GSSM containing the more recent version
of GSS software.
3. Obtain an earlier software (.upg) file.
4. Downgrade your GSS device.
5. Restore your GSSM database backup corresponding to the downgraded
version of GSS software.
Do not attempt to restore an earlier version of the GSS software than the earliest
GSSM database backup that you have available. For example, if the earliest
version of the GSS software in your possession is Release 1.1, and your earliest
GSSM database backup is for Release 1.1, do not downgrade to a release of GSS
software earlier than Release 1.1.
To restore an earlier version of your GSS software:
1. Verify that the roles of the designated primary and standby GSSMs have not
changed. The changing of roles between the designated primary GSSM and
the standby GSSM is intended to be a temporary GSS network configuration
until the original primary GSSM is back online. Refer to the
“Verifying the
GSSM Role in the GSS Network” section of Appendix A, Upgrading the GSS
Software.
2. Perform a backup of your primary GSSM as described in the “Performing a
Full Primary GSSM Backup” section.
3. Obtain an earlier software version as described in the “Obtaining the
Software Upgrade” section of Appendix A, Upgrading the GSS Software.
