All existing zCX instances must be upgraded to 1.26.0 and successfully complete the user data migration before applying this maintenance.

Bringing all of your zCX instances up to the zCX 2.0 maintenance level eliminates a prior requirement for IBM Container Hosting Foundation for z/OS (5655-HZ1) entitlement to use zCX.

Once all upgrades are successful and all zCX instances are successfully restarted, you can safely disable and remove the IBM Container Hosting Foundation for z/OS (5655-HZ1) product registration in the IFAPRDxx member.
Note: Remember to issue the SET PROD command to specify the updated member as active on the system. If necessary, update IEASYSxx to point to the newly edited member.
1.26.0

OA65991, OA66521, OA66541, OA66542 and OA65770.

After applying this maintenance, all existing zCX instances must be upgraded to 1.26.0 and successfully complete the user data migration before applying the 2.0.0 maintenance.
