Biggest thanks goes to the sysplex parallel sysplex development team. Reconfiguration is much more robust and easier to manage than when we started out in the mid 90s.
We just finished upgrading both CECs in our production complex, one push-pull at a time, about three weeks apart. I built two new CFRM policies in advance: first one (interim) with one new CEC defined, second one (final) with both new CECs defined. 1 Move all structures to the old CEC *not* being replaced in round 1. SETXCF START,MAINTMODE,CFNM=old-CEC-being-replaced SETXCF START,REALLOC 2 Shut down and disconnect old CEC being replaced. 3 Swap out and connect first new CEC. 4 Activate the interim CFRM policy from the (up and running) old CEC. SEXCF START,POL,TYPE=CFRM,POLNM=interim-policy SETXCF START,REALLOC Three weeks later, perform a similar drill with the other new CEC and the final CFRM policy. Voila. 15 years ago this would have been much harder and scarier. . .

We followed this procedure for our sandbox sysplex, we will do the same for test and production.
