Hello,

I gonna upgrade Unity3.1(6) w/Exchange2K to Unity4.0(5) w/Exchange2K

on the same Server.

The main steps are as follows,

1. Backup data(to a safety place, use DiRT)

2. Reinstall OS, SQL,Exchange2K etc. and Unity 3.1(6). ( Now we got a blank

new Unity system on the same server)

3. Recover old data(from safety place) to new Unity3.1(6) System.

( use DiRT)

4. Upgrade new Unity3.1(6) to Unity 4.0(5).

My question is , that in step 3, will lose any subscribers' information?

Any anybody has similiar experience?

Any issues that could happened?(like some call handlers missing?)

(I already run DBWalker, 0 error. And the DiRT finished without any errors)

I would like to share the experience with you , and I will update the status.

Howard
