We recently upgraded our TEST system LPAR from V6R1 to V7R2. Prior to performing this upgrade, one of the pre-requisites was to increase the size of the LIC area on disk to accomodate the increased code size at level V7R2.
Unfortunately, we are now forced to roll back to V6R1 because a key portion of our ERP package will not work at V7R2. Please don't ask why management dropped the support for our ERP package a couple years ago...or I may have to launch into a tirade of cursing...lol
At this point, using a V6R1 SAVSYS tape prior to the upgrade, we are planning to (a) Recover the Licensed Intgernal Code followed by (b) a Restore of the Operating System.
Has anyone had experience doing a LIC/OS restore from a SAVSYS tape? We have an HMC that conrols poth the Production and Test LPAR's so we're hoping that once we setup the IPL device correctly, we should be able to (semi-painfully) re-install the LIC and the OS back to V6R1...
Any thoughts/comments would be appreciated.
