Prepare the Replication Server for upgrade.
-
Back up the RSSD or ERSSD. The upgrade process makes changes to
the RSSD or ERSSD that you cannot roll back if the upgrade fails. Restore
the RSSD or ERSSD from the backup if the upgrade fails.
-
If you plan to install the Replication Server software in a directory other
than an existing Sybase version directory, verify that the interfaces
(sql.ini) file is accessible.
-
Read the release bulletin for your platform for any special installation
instructions about mixed-version environments, installing, or upgrading.
-
Use rs_helpsub and rs_helpdbsub to check that all subscriptions are valid. The upgrade fails
if there are subscriptions that are not in a valid state before upgrading.
-
Install Replication Server, following the instructions in the Replication
Server Installation Guide for your platform.
-
Verify the system-wide and route versions and upgrade to version 12.6 if
necessary:
-
Execute sysadmin system_version on the current Replication Server.
If the system version is 1260 or later, you can upgrade your
Replication Server now. If the system version is earlier than 12.6,
proceed to step 6b.
sysadmin system_version
go
An example of the output is:
The current system version is 1102.
-
Set the system version on the ID Server to 1260:
sysadmin system_version,1260
go
If setting the system version is unsuccessful, this message appears and
you must proceed to step 6c:
The system version could not be set. The specified
version ‘1260’ is higher than the lowest
Replication Server version in the system ‘1250’
If setting the system version is successful, this message appears and
you can proceed to step 6d:
The system version has been reset from 1102 to
1260
-
Upgrade Replication Server to 12.6 and set the site version to 12.6 for
any Replication Server in the domain that has a version earlier than 12.6.
Repeat step 6b.
-
Execute sysadmin system_version again on the current Replication
Server. If the system version is 12.6 or later, proceed to step 6e.
-
Execute admin show_route_version to verify all route versions are
1260 or later. If the route version is lower than 12.6, see “Upgrading
routes,” in Chapter 6, “Managing Routes” in the Replication Server
Administration Guide Volume 1 to upgrade the route version. After
you upgrade the routes, you can upgrade the current Replication
Server.
