Procedure is very easy.
1) Start reconfiguration dialog moving CKPT2 to CHPT1.
Checkpoint is now on disk.
2) SETXCF FORCE old checkpoint
Delete old checkpoint off coupleing facility
3) Define new CFRM policy with larger checkpoint
4) Activate new CFRM policy
5) Start reconfiguration dialog assigning new checkpoint to CKPT2
6) Continue dialog and move CKPT2 to CKPT1
New CF Checkpoint is now CKPT1
7) Delete and reallocate new disk checkpoint
8) Start reconfiguration dialog assigning new checkpoint to CKPT2
FINI.
