Upgrading from R6 to R9.1

Hello,

We are prepping for an upgrade from R6 to R9.1, I have a production box
that is V5R1 and a test box that is V7R1.

I can load a copy of my V5R1 R6 production XA environment on my new V7R1
box, but some program objects fail to come over due to date references.
I cannot run ANZOBJ or ANZOBJCNV because they do not exist on my V5R1 box,
and I cannot upgrade current box as it has no OS support.
However the data comes over fine (cursory check, RSTLIB reported no errors
with AMFLIB*, unlike AMALIB*).

I'm wondering if I need to worry about this since the R9 migration tool
migrates the data, perhaps an incomplete AMALIB is ok?

I am awaiting the media from Infor, but thought I'd ask if anyone else has
gone this route.

Appreciate any tips you may have.

Thanks!
