You did not indicate if you are using an ICF or not. I would run the sizer for the CF22 level. Update your current policies to match, and add the new CF to the policies. The major difference between CF17 and CF22 is the size of the structures. Options: 1) Add (I guestimate) 20% To your current structure sizes and play with the numbers. Take a SWAG and look at the results. Wash/Rinse/Repeat until you are happy with the results. 2) Contact IBM for assistance and/or guidance
In any case, hardware wise, you are looking at a "hard down". -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Juergen Kehr Sent: Friday, September 6, 2019 6:47 AM To: [email protected] Subject: Migration from z114 to z14ZR1, CF structure sizes Hello, we’re planning a migration from our z114 to a z14ZR1, therefore we have to bring our CF policy from one which supports CFLEVEL=17 to one for CFLEVEL=22. Because of hardware dependencies there is no way to have a z/OS system which has one CF with the old CFLEVEL and one with the new CFLEVEL up and running. On the old z114 one we could attach the old CF, on the z14ZR1 on the new one. But as far as we understand this would be a requirement for using the SIZER tool (see CFSizer alternate sizing methods: https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ibm.com%2Fsupport%2Fpages%2Fcfsizer-alternate-sizing-techniques&data=02%7C01%7Callan.staller%40HCL.COM%7C311a9ff01d4346f36f3508d732bff5aa%7C189de737c93a4f5a8b686f4ca9941912%7C0%7C1%7C637033672389291945&sdata=EVrK0Tnnhp4xxZ5ru1jhwoyHyDbeFJEizH7PWp%2Bj1nE%3D&reserved=0). Using CFSizer in our case would be fairly complicate, because we don’t know the input values used in former CFSizer runs to lead to the existing values in our policy. Furthermore we can’t reproduce this, because CFSizer only supports the current CFLEVEL=23, so we can’t try to reproduce the old input values for CFLEVEL=17 via looking to the results they produce. So we urgently would need any good idea, how to get the new structure size values when migrating from CFLEVEL=17 to CFLEVEL=22. Thanks in advance for any help. Kind regards.
