moving running workitems from one production system to another

[skidmore.s@pg.com]

Hi Everyone,
 
Here's an interesting question I got today that I could use some input on...we
are currently on SAP 4.5B and are planning a large cutover of one of our SAP
systems.  And when I say cutover, I mean moving financial activity from one
production system (SAP 4.5B) to another production system (SAP 4.5B).  The
kicker is we will have thousands of running work items in various workflow
applications that would need to be 'moved'.
 
A few questions:
The first stage of the cutover would be to rename one of the SAP systems to
something new (what this means from a basis standpoint I'm not sure).  What
should I watch out for in terms of running work items on the system that will be
renamed?
 
The second stage is actually moving the activity from one system to another with
a proposed 'hard' cutover.  Is it possible to 'lift' the in-process workitems
from one box and put them in another box so they show up in the new box at the
exact same point in the workflow?
 
Has anyone tried anything like this before or have any ideas/thoughts/concerns?
 
Thanks,
Sheldon Skidmore
