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 the GSS software. For example, if you
want 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
protect 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 that contains the more recent
version of the GSS software.
3.
Obtain an earlier software (.upg) file.
4.
Downgrade your GSS device.
5.
Execute the
gss disable
command.
6.
Execute the
gss enable
command.
7.
Restore your GSSM database backup that corresponds to the downgraded
version of the 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.
