Each structure definition in the CFRM policy requires a PREFLIST to indicate where to allocate the structure. The PREFLIST contains one or more names as defined at the top of the policy. Although IBM recommends that NAME match the CF LPAR where it resides, that correspondence is not required. (I never even saw that recommendation until just now when I looked in the book.) For 15 years we have always used NAME to match the CEC because we name ICF LPARs by the sysplex to which they belong. That is, sysplex X will use LPAR CFPLEXX on all participating CECs. NAME would not be unique if we tried to use the ICF LPAR name.
Bottom line is that NAME can be anything you choose as long as it follows the syntax rules. I wish I could tell you that I have done this exact same thing, but it should work fine. *Add* a new CF NAME to your policy like this: CF NAME(some-unique-name-of-your-choosing) TYPE(new-CEC-type) SEQUENCE(new-serial-number) PARTITION(new-LPAR-number) ... For each structure, include PREFLIST(old-name,new-name). Today only old-name will be found at IPL, so all structures will allocate there. After installing the new box, only new-name will be found, so that's where all structures will allocate. You will be just fine today and after the install. It can't hurt to try this now. If the CFRM policy compiles OK, you're 80% of the way there. Then activate the policy: SETXCF START,POL,TYPE=CFRM, POLNM=new-policy-name. If it activates with no errors, you're pretty much guaranteed that the same policy will work fine with the new CEC in place barring typos in CF definition. When you're all done, remove old-name from your policy. We've always had multiple CECs, but the principle is the same. We recently replaced both CECs on the floor using a similar strategy. At no point did we have to IPL into an untested configuration. . .

Mr Kawkabani, I will use CFRMPOL to refer to newly created policy. What about ARM and SFM policies that I have created using IXCMIAPU and are named differently. How can I use them. Still searching for how to create new CDS, BPXMCDS, LOGR (hundreds of structures)and WLM policies and how to make system to use them right from the IPL.. Mr Robinson, My problem is I have only one ICF partition on each boxes (Old and New) and will not have cross coupling facility links. Both of the CF names are COUPL01. Can I format CFRM Policy with duplicate CF NAME COUPL01 for each process types (2818 and 2086, serial number will remain the same). If it is possible I can use same CFRM policy and before shutting down the last LPAR for processor migration, I can change CF configuration to match the new processor. I am planning to bring in sandbox LPAR in the plex first and should be able to use FORCE command to get the Coupling facility correct before bringing in any proper systems in the PLEX..i do agree its risky and need guidance. Thaks once again for you valuable suggestion, its much appreciated..
