Different Approaches to Restore Exchange 2010 Database
Well, the Exchange administrators can take different approaches to restore Exchange 2010 database from one server to the other. The approaches that can be taken are as follows:
- Use of Database Portability feature
- Use of Mailbox Server Recovery
- If the mailbox server is present in Database Availability Group (DAG), then the database can be activated on another DAG member that contains a copy of the database.
Note – Database Portability is the most beneficial to restore Exchange 2010 database to a different server.
Database Portability feature and its functionality
This has been first introduced in Exchange Server version 2007, and available in Exchange 2010, Exchange 2013, and Exchange 2016 as well, the Database Portability feature owns a significance. Its basic functionality is to move or mount exchange 2007/2010/2013/2016 database from one mailbox server to the other which is in the same organization. Users can move the mailboxes to distinct Storage Group on the same server. Once the mailboxes are moved to a different server, they can be reconnected. However, this feature cannot be used to move the public folders of the database from one server to the other.
- Its key points
- Mailbox database can be moved or mounted into another mailbox only in the same organization.
- The mailbox database to be moved or mounted should be from the same or newer Exchange version. The reason being, an older Exchange version is not valid when the need is to move or mount mailbox database from one server to the other.
- The mailbox database cannot be moved from Public Folder of Exchange Database i.e. pub.edb files of Exchange.
- Process of moving/mounting Exchange Database using this feature
- Yield the log files and database to the Exchange Server where it is required to mount or move the database. This can be accomplished by restoring the database from the backup, or the new server can be attached to the same Storage Group where the old server was connected.

- Confirm the shutdown status/state of the Exchange database. This can be done by opening Exchange Management Shell and then going to the folder that contains the database file, followed by running the below-mentioned command:
Figure 2 (Indicative): Confirming Exchange Server’s shutdown status
- If the Exchange database is in a dirty shutdown state and transaction log files are also available, then execute ‘soft recovery’ of the Exchange database.
Note – This step does not cause any change in the transaction log file, and thus there is no situation of data loss. However, if the database is in a ‘clean shutdown’ state and there is an absence of transaction log file this step is not needed.
- Run the command line by replacing ‘E00’ with log file prefix of the database that is present in a folder of the transaction log file. This is because, here, it is assumed that the database is in ‘dirty shutdown’ state.
Figure 3 (Indicative): Running the command line
- Create a new mailbox database in the new mailbox server where it is required to mount the database. Also, allocate new location for transaction log file and database that is different from the existing location.

- Copy the log files and Exchange database from the present to the new location that was assigned during the process of creating the new mailbox.

- Mark the database as ‘Overwritable.’
Figure 6 (Indicative): Marking of the database
- Get ready to ‘Mount the Database’
Figure 7 (Indicative): Mounting of database
- The process of mounting or moving database is completed, but the users of the mailboxes still go to the old database name and server.

- Point users to the new mailbox server by upgrading the Exchange Server properties.
Figure 9 (Indicative): Users pointed to the new mailbox server
- After upgrading the changes, the ‘users’ accounts that are available in new mailbox server can be seen.
Once the move or mounting process is completed users can reconnect the mailboxes under assumptions that are as follows:
- In Outlook 2010 and 2007, and Outlook Web Access (OWA), clients will get the access to the new database automatically.
- In Outlook 2003, users need to upgrade the accounts or profile manually to connect to the new database.
- The upgraded accounts of users should use Active Directories (AD) for a copy.
Well, Database Portability can fail to move or mount Exchange database owing to its manual characteristic. Manual ways require in-depth knowledge and experience to achieve the requirement.
