And I thought I was bad. We upgraded to 8.4 about 4 years ago.
Part of the delay was the two years it took to migrate our 2.1 indexes to the
8.4 index tables.
And now we are headed off of z/OS to AIX, again migrating data.
But this seems to be much faster. Started off-loading mid July 2014,
though we are still adding reports to CMOD 8.4 on z/OS.
Seems until we upgrade the AIX system from CMOD 8.5, z/OS line data reports do not
index on AIX 8.5 CMOD. Or so the documentation states.
You may want to find out from IBM sooner than later about index and data migration from 2.1 to more current versions.
