We are planning to migrate from 5.2 to 5.3 some time during 2008. To achieve this we will make a second-level z/VM installation, test all we can, migrate the system directory (users, Linuxes, etc.), modify the ipl address at the HMC, IPL the 530RES disk ... and pray.
This has been always the traditional way we have installed any new VM version since VM/ESA 2.1 and so far it has been a quite good practice. Just don't know if that was due to good luck or the result of our prayers... ;-) I think I have the last z/VM 4.4 --> 5.2 migration in WORD format (I always try to copy every screen into such docs just in case that something goes wrong and must report to IBM with first-hand data about the problem). If it can be some help just let me know (but it will take me some time to translate it into english). No problem. Saludos, José R. Barón Dpto. Sistemas CALCULO S. A.

Peter Peter E Abresch/EP/PEP 01/23/2008 03:59 PM To Linux on 390 Port <[email protected]> cc Subject z/VM Version 5.1 to z/VM Version 5.3 migration? We have to upgrade our z/VM version 5.1 to version 5.3. We run z/VM only to support our Linux guests. We reviewed the z/VM Migration Guide and see in chapter 2 where the following is hinted at: Support is provided for simplified migration to z/VM V5.3 from either z/VM V5.2 or z/VM V5.1. We do not know what this means and can not find any elaboration anywhere? Does anyone have a clue? We also can use z/VM Getting Started with Linux on System z to install z/VM into another LPAR. This is how we originally installed and configured z/VM version 5.1, but it was a new z/VM install back then. If we go this route, we will have to redefine all our Linux users and mini-disks all over again or is there some type of migration tool or assistance. Is there a manual or cookbook type doc that better documents this migration process? Would we migrate our Linux guests using the ?big bang? approach or is there a more subtle approach? As always, any help and assistance is much appreciated. Thanks.
