Sybase Control
Center does not support downgrade. Back up your SCC installation directory so you can manually
restore the previous release if necessary.
This procedure applies only to upgrades from Sybase Control Center 3.2.x to later versions
in the 3.2 series
because these versions are installed into the same SCC-3_2 directory. If you are
upgrading from SCC 3.1 or SCC
3.0,
you do not need to prepare to roll back—just keep your old installation directory and
continue to run SCC from it. Avoid running the new and old versions of SCC
simultaneously unless you have assigned them different ports.
- Copy the SCC
installation directory for the older version (SCC-3_2, SCC-3_1, or
SCC-3_0) to a
location outside the parent Sybase
directory.
- Install the new version of SCC and perform the upgrade procedure as described
elsewhere in this guide.
- Follow these steps if, after performing the upgrade, you need to roll back:
- Uninstall the new version of SCC—see Uninstalling.
- To reset environment variables, run the SCC installer for the version you are
rolling back to. Any configuration you enter in the installer will be
overwritten when you restore your old installation directory. Do not start SCC
from the installer.
- Copy the backed-up installation directory to its original location in the
file system.
