Restore Exchange DB after Recreation of mailboxes to New Exchange(low priority)

Question

Hello to Everyone
Recently one client of mine had a problem with an exchange migration that he tried (2010 to 2013) and he needed to restore his old EDB  from windows backup to restore 10 Mailboxes that he had already migrated. We run the whole procedure with  eseutil,
ISINTEG  etc.  The problem was that the client had already deleted the mailboxes and the AD Users and recreated them on a new database. When I tried to export or move the mailboxes the Power Shell reported unknown error and as I understood tried
to Read from active directory GUID and couldn't find the same and Stopping.
We solved the problem with the OST to PST files relied on the computers but I would like to hear from your experience if we had other Alternatives?
I could think only to restore Exchange and the domain controller on a VLAN so they have the same AD Objects and then Export all mailboxes to PSTs and then Re import them to the New Exchange Server.
Thank you

Not sure the steps you took, however based upon your brief explanation it sounds as though you were able to restore and rollup the logs using eseutil, correct?
Did you then use the RDB process to mount this DB onto an Exchange 2010 Server?
Assuming the above is correct you should then be able to restore the mailbox from the source DB into a temporary user mailbox as outlined here

If the above doesn't work for you the other option would be to use a 3rd party tool like Lucid8's DigiScope
http://www.lucid8.com/product/digiscope.asp which would allow you to easily open the Offline 2010 EDB to see all the mailboxes and their contents.  You can then easily export to PST or directly
recover/migrate data from the offline 2010 EDB into the 2013 Production Exchange Server
Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003
--> 2007 --> 2010 --> 2013 with Lucid8's

1. Yes Troy that is correct. I soft repair the db but it was continuing to be in dirty state. So I hard repaired it and came to a clean state.
2. I then Created a recoveryDB and tried to move mailboxes to temp mailboxes or export mailboxes etc.
3. There was no luck with the above, the power-shell reported that the mailbox GUID has changed and don't match with the AD signature, I am thinking this is probably because  the client has already recreated all the mailboxes to a new db with the same
usernames-mails. In the end and after one day of tries I recommended a third party tool that I tried and I have seen that finds all the data of the mailboxes or if we have the OST of the users to convert them to PST. They used the second suggestion with OST
and I restored everything.
I posted this problem for brainstorming and if anyone else had the same problem or might have an idea why this happened. :)
Thanks
