I dimly recall (hey, it's all pretty dim these days) a long ago chasm
crossing where we had to 'reformat' the RACF data base. I can't imagine
anyone still running such an ancient release. Unless you're resurrecting a
copy of a decades old data base, a 'template refresh' should be sufficient
to get the old coot running. That process used require a utility run before
IPLing a new level. For several OS releases now an in-storage update is
done dynamically, and the utility--if you bother to run it at all--is done
after IPLing a new level.
Just remember that a RACF data base is quintessentially a bunch of ones and
zeroes until it becomes the 'primary' data base in a running system. At
that point, what you got is what you have. An old data base that may be
'usable' with updated templates may lack so many profiles and modern
options that it's useless for your normal operation. In other words, you
can try this at home, but don't try it at work in a production environment.

Even if you are not on a supported migration path, you can always try to
copy the database over and apply the new templates. The worst that will
happen is it doesn't work. In that case, you can use the brute force
method. Run the RACF DBSYNC freebie comparing your current database to
an empty file. It will produce a reasonably complete set of RACF
commands to make your new database look like the old one. (Users
created in the new database will have default passwords which they must
change at first logon.) In any case, the effort should be measured in
days, definitely not months.
I want to know from a technical perspective if some one needs to migrate
an existing system from an older version of OS (say MVS/ESA, OS/390 etc
to Z/Os) what is the impact on RACF?. Would migrating the RACF to a
newer version be a big enough Project(like a 6 months to 1 year kind of
project)?. Or as in any migration from one version to another, RACF is
also automatically handled?. Please advice.
