Keep in mind the following upgrade considerations introduced in PingDirectory 9.x versions.
If you plan to upgrade servers using a mixed-version environment where one version is
earlier than 7.0 and some of the servers are still using the admin backend while
others have been updated to the topology registry, do not attempt to make size
changes to the topology. You cannot remove any existing servers (using
dsreplication disable) or add new servers (using
dsreplication enable) when in this transitional state of
partially-updated servers. When a topology has been completely migrated to a 7.0 or
later version with the topology registry, changes to the topology size are allowed,
even in mixed-version environments (for example, mixed 7.3 and 8.3).
Cleaning replication history
When cleaning replication history from a Directory Server, you must now use the new
--performLocalCleanup. If you have existing automation around
disaster recovery, the previous method of running
remove-defunct-server without bind credentials no longer
performs this replication cleanup step. For PingDirectory versions 22.214.171.124 and later, update any
existing automation to use the
Spring configuration properties in PingDirectory suite of products admin console configuration files before PingDirectory suite of products 126.96.36.199 are not compatible with the most recent admin console bundled with 188.8.131.52 and later versions of PingDirectory suite of products because of major updates to Spring dependencies. Attempting to use these older configuration files results in the console failing to start.
If you are using older PingDirectory suite of products admin console configuration files, update them by replacing the following excerpt in the old application.yml file:
# 1 year. Update the corresponding value in MvcConfig if this changes.
add-mappings: false # use our custom mappings instead of the defaults
