Exchange Server Crashed, is it possible to migrate the EDB from the crashed Exchange Server (VM) into the new Exchange Server.

I have the EDB of a failed Exchange server (VM) and emails in PST for each user. I'd like to know if it's possible to create a new VM, install exchange and connect to the old EDB, I don't believe this is worth the time but doesn't hurt to ask.

Which one is the version of Exchange that you are running?

Assuming that only your operating system and/or the exchange application was affected. And that you still have all your database files in a consistent state. You can install Exchange in recover server mode, and it will work exactly as it was setup before.

These ones are the steps:
1. Take the Original Exchange server out of the network.
2. Reset the computer object account associated to the Exchange server (i.e. open Active Directory Users and computers, look for the computer object, right click on it and reset the account.)
3. On a brand new Operating System setup the name of your previous exchange server and join it to the domain.
4. Install all the exchange server prerequisites.
5. Install Exchange Server in Recover server mode from the command prompt or powershell:
Setup /m:RecoverServer /IAcceptExchangeServerLicenseTerms
(This is the command for the last versions of Exchange, if you are using a very old one, i.e. 2003, it will slightly change)

By the way...

Despite of the previous process, the answer is yes. Only with the EDB you can recover all your mailboxes. Even if you construct a new Active Directory.

One of the hard requirements that you will have is to use the same "Exchange Organization name", assuming that a new and separate Exchange server is installed. (This process works even if you create a brand new forest with a new Exchange implementation, of course, there are many steps involved with this, but it is a possible and supported process).

As commented above create a VM with same computername, IP address. Copy this EDB and recover the failed Exchange server.
Please specify the version of Exchange server failed.
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

To restore the server or at least EDB file, you need to restore it in same Exchange organization so you would need to start off from restoring the Active Directory. Second point is to have same database schema version you also need to know what was the CU on the crashed Exchange server.

Database portability -

Other option you have is to use third party software which can recover the data from EDB file directly and export to PST file.

Did you checked my article.

If you don't have DAG, you can skip DAG steps, rest all is same for standalone server.

Since Exchange Server is Crashed, it is possible that the EDB File is corrupted or chances of Data loss is possible. To Recover failed Exchange Server, you can try /m:RecoverServer Setup [Not sure about your Exchange server Version.]


If still, you are not able to reconnect the OLD EDB Database then first you to convert the Database into " Healthy State" and then move into Exchange Server.
This Complex process can be done perfectly using SysTools Exchange Recovery Tool. Software not only repairs the Corrupted EDB File but also help the user to move Exchange Mailbox into Live Exchange Server Account.
