If it does exist, and already contains a Replication Server
installation, you are warned that you will overwrite the older version. Click
Next.The
installer checks that the version you want to update is compatible with the
version of Replication Server you are installing. If the version is
incompatible, the Check Upgrade Incompatible Version dialog appears, and you
see this:
Warning: The current "Sybase Replication Server" in your
destination directory is not compatible with this version upgrade; some bug fixes may be unavailable
if you proceed. See the release note for more information.
You
may see a similar message if your Replication Server is an out-of-band release,
such as an emergency bug fix, one-off, controlled, or instrumental
release:
Warning: The current "Sybase Replication Server" in your
destination directory is an out-of-band release; some bug fixes may be unavailable if you proceed.
Verify that the bug fixes you need are in this newer version before proceeding with the upgrade.
If
you see such messages, click
Cancel to stop the
installation process. To override the error and continue with the installation,
select
Proceed installation with incompatible version
and click
Next.
Warning! Upgrading to an
incompatible version may cause software regression. SAP recommends that you
cancel the installation and obtain a compatible version of Replication
Server.
Note: If you perform the installation in a silent, or
unattended mode, and the versions are incompatible, the installer prompts
you to rerun the installer with this argument, then
quit:
