RE: Migrating 170 to new i5 520

If this is not an upgrade but a new system, you can build the new system
from scratch.  You cannot restore user profiles or configuration.  But
if you create all the user profiles before you restore your user
libraries, you have a good chance of getting your applications and
security correct with little tweaking.  It all really depends on your
size and complexity of your environment.  I can build an authorization
server from scratch and have it running in four days.  Two user profiles
own and run everything, then I have to add the programmers.  Public is
Exclude, one group profile owns the files and programs and another
profile is granted access to run the applications, which run under
owner.

It takes another day or two to get the programmers the proper access.
This is a very simple one application client/server base system that
uses SNA for mirroring and remote communications.

If you can install and test, document what need to be changed, then
re-import the data and go.

Still much easier to upgrade to compatible OS, SAVE / RE-Load from tape,
test and document changes needed.  Then repeat when ready to switch
over.

Subject: Migrating 170 to new i5 520

I am reading over the instructions in Appendix D of the Backup &
Recovery guide, and I'm curious about one thing:

Why would I want to _replace_ the OS on the new 520 whenever it is
already installed and running???  What is the reasoning behind this and
why can't I just move over my User Libraries, Security, and
Configuration data with just simple Save/Restores?  

The manual doesn't explain this, at least not that I have found...

Can anyone give me a good reason?  We are a very small shop, and if I
had to, I could just recreate the user profiles and devices on the new
520 manually.
