RE: 730 to 825 migration

[Jeff Bull <Jeff.Bull@xxxxxxxxxxxxxxx>]

Personally, I do not like (and am inclined to strongly resist) such requests
as this.  It is my experience that inventing your own procedures for
hardware or software uprades is fraught with many problems, not least of
which is, if it wipes out, where do you go for help? IBM are unlikely to
help without big-bucks being waved, and they will almost certainly take you
back to the conventional or approved route.

If the system belongs to a client (ie not your own system) then you must
consider your own legal and other obligations to clear up a mess.

If the client is adamant, and cannot be encouraged to take the correct
route, I would insist they come up with the extra cash to install a brand
new system, side by side with their current system, then migrate the
configuration, security, applications and data etc.  A trade-in deal on
their 730 after they are up and running (say, in two or three months)
shouldn't be too difficult to work out.

Subject: 730 to 825 migration



I am planning to migrate from a 730 at v4r5 to a new 825 partition at v5r2.
My client does not want his 730 to be upgraded to v5r2 as he is concerned
with having problems in v5r2.  He is requesting that I NOT do a "by the
book" migration where the source system is upgraded then the target
partition loaded from scratch from the save of the source system. I have
done two of these "user data" migrations before but both were very small
systems (600, 170).  I know the issues with QGPL, QUSRSYS, QDLS, IFS, etc.

Two requests.

I would like to hear from all of you if going from v4r5 to v5r2 has given
anyone problem.  Are the clients fears founded?

Please comment on the non-conventional migration.  Is this a reasonable
request?
