Object conversion was a huge issue.
If the object kept observability, then good chance it could be converted.
If not, a 6.1 version of the object was required.
Most 3rd party vendors do NOT keep observability, thus you need to reach out to them for the 6.1 version.

Subject: RE: New purchase
The big thing when going to 6.1 and beyond is Object Conversion. Read this:
http://www.redbooks.ibm.com/redpapers/pdfs/redp4293.pdf
Upgrading from V5R3 to 6.1 was supported. Technically one should then upgrade from 6.1 to 7.2, then 7.2 to 7.4. Basically IBM only supports upgrading from x-2.
Ideally you upgrade your 520 to 6.1 then to 7.1.
https://www.ibm.com/support/pages/node/6023368
Find some machine (see the above link) which will upgrade from 7.1 to 7.3 then 7.4. Then plop it on your new machine. Most P9's will support 7.2 and above so you could continue the upgrades on the new box. There's a small subset of P9's which support 7.1 (see above link).
If you are going to skip any of these intermediate steps then you're in for a big chance to make a mess. Some may look as this as a good time to start out fresh. Normally they are hobbyists. There's a good chance you'll mess something up. This ain't an AS/400 where you just restore a few libraries, user profiles, etc and you're good to go. Not that it can't be done, but there are a lot of stories out there of people who then spend months cleaning up the mess.
You cannot skip Object Conversion. Read that redbook religiously. If you have old software you're planning on getting rid of you want to dispose of it prior to the upgrade. Their uninstall program likely won't run on anything at 6.1 and above. Again, this ain't an AS/400 where you delete a library and the object owner user profile for that software and you're good to go. They may have hooks throughout the IFS, system directory entries, etc.
However, you may find this interesting reading:
Preparing for the migration from a IBM i model that does not support IBM i 7.4

Again, you still cannot skip Object Conversion. RTF redbook.

At this moment I'm not sure I need a used machine.
I'm currently running V5r3. I was told I need to update it
to V6r1 before I go
to V7r4.
And that's why I asked for a used box.
I know I can do the update to V6r1 on the current i5 520.
I can't take the chance to do the V6r1 on the live
machine.
I have found conflicting reports that some people have
tried to go from V5r3 to
V7r3.
Some people were not able to make the jump. I haven't
heard why. Some people
have
made the jump successfully.
I'm thinking of trying to:
1. Keep the i5 520 running live at V5r3.
2. Purchase a Power 9 running V7r4.
3. Try to convert everything running on V5r3 to V7r4.
4. If I can't do the upgrade directly then I will purchase a
used box running
V6r1.
Currently I'm running the i5 520 with System ASP 105G
Percent Used 43%
WRKSHRPOOL shows Main storage size (M) . : 892.00
DSPHDWRSC TYPE(*AHW) shows two 512MB Main
Storage Cards
I would only need the used box for the conversion to
V6r1
Thanks,
Gary

What are the size requirements for the used machine? DASD, memory, etc.?

Subject: New purchase
I'm looking for a business partner so I can purchase a new box. It will be
the smallest box IBM makes to replace an i5 520 that I currently have.
I am also looking for a used box somewhere between a
520 and a new box so I can install the os increments and our current
software to make sure everything will run before going live with the
upgraded OS. Currently I'm running V5r3. I'm guessing I will need to
install V6r1 on the Used (Interim) box with our current software to test it
before going live. Then I'm guessing I will need to install V7r1 on our
current 520 that I have with our software to test it to make sure everything
will run. Then I'm planning on putting our software on the new box running
V7r4 and testing it.
If you are a business partner please email me privately with the hardware
discount and software discount you feel comfortable with for the new box.
If anyone has a used box for sale please email me privately.
Thank you,
Gary Kuznitz
