Attention:

On IBM MQ for Multiplatforms, we cannot reverse queue manager migration to remove the effect of changes. This restriction applies whether your enterprise uses the Long Term Support (LTS) release or Continuous Delivery (CD) release model.

On IBM MQ for z/OS, you can reverse queue manager migration as long as you have migrated from an earlier LTS release to a more recent LTS release, and the earlier LTS release had the backwards migration PTFs for the more recent LTS release installed before the migration started.

See IBM MQ release types for further information.
