If you have already upgraded the existing cluster nodes to a support
package or patch level later than 2.2, you must upgrade the new node to that same support package or patch
level.
Note: This step is necessary only if you have upgraded your Unwired Platform version 2.2 cluster
to a support package or patch level later than 2.2.
Go to the Release Bulletin for the
latest 2.2 support package
or patch level to which you have upgraded the cluster and follow the instructions
there for upgrading the Unwired Server node you just installed to
the same version as the rest of the cluster.
