Upgrade to 5.2 first, then from there to 7.5.2. I do not think upgrading from 4.5 directly to 7.5.2 is supported. Involve your support provider to get advice directly from IBM.

you can also go via any 6.x Version as we did it.

Pay attention on each routine:

In past (before 5.x) you could do:

MyRoutine(Arg1)
Arg1=Arg1+25
Return(Arg1)

Now you have to change it like this:

MyRoutine(Arg1)
Arg2=Arg1
Arg2=Arg2+25
Return(Arg2)
