12.2 Migration
A migration is installing Identity Manager 3.6.1 on a new server, then migrating the existing data to
this new server. Follow the
Chapter 4, “Basic Identity Manager System Checklist,” on page 39 to
verify that the installation is complete.
The advantages are:
Š
There is minimal downtime for the drivers
The disadvantages are:
Š
Requires new hardware
If you are performing a migration, proceed to Chapter 14, “Performing a Migration,” on page 89 .
12.3 Multiple Servers Associated with a Single
Driver Set
If you have multiple servers associated with a driver set, you can perform an in-place upgrade or a
migration on one server at a time. If you don’t have time to upgrade the servers at the same time, the
drivers continue to work with the different versions of Identity Manager until the upgrades for each
server can be completed.
The Identity Manager engine is backward compatible, so the Identity Manager 3.6.1 engine can run
Identity Manager 3.5
.x drivers without problems.
WARNING: If you enable features for drivers that are supported only on Identity Manager 3.6.1,
the drivers stop working on the servers with mixed versions. The older engines cannot handle the
new functionality. This breaks the drivers until all servers are upgraded to Identity Manager 3.6.1.
