This is a truly very much archived process on the web and, yet as of late I have needed to change the database way inside my creation DAG condition, so I felt that I would impart to you some of “dissatisfactions” that I had which will allow you to “prepare” should you have to do likewise.

Exchange Server 2010 – the emphasis is more on how winning conditions inside your own condition (or without a doubt because of this post) can influence the way toward changing a DAG database way.
The procedure
It most likely bodes well to give an abnormal state outline of the entire procedure of changing the ways of DAG empowered databases – this is given at an abnormal state beneath:
- Reinforcement your databases! – This may appear glaringly evident, however guarantee that you have a working reinforcement of any database that you mean to adjust.
- Descent the dynamic duplicate of the letter drop database.
- Evacuate all DAG duplicates of the objective database.
- Ensure that you keep the physical records (both Transaction Logs and Databases) of the database duplicates that you have expelled.
- Consider – or compel a Domain Replication and after that invigorate both the database rundown and duplicates inside the Exchange Management Console.
- From inside the Exchange Management Console right tap on the got off duplicate of the database and from the setting menu select the “Move Database Path” alternative.
- Pick another area on your Server for the Exchange EDB way (you can likewise choose another area for the exchange logs if you wish to).
- On every DAG hub that will house duplicates of the databases move the physical records that you kept in stage 4 to the applicable areas.
- Once the database has been moved, consider area replication to happen (or drive it on the off chance that you can’t pause).
- Mounting the database.
- Re-include your Mailbox Database duplicates.
For stages 2,3,6,7,10 and 11 (above) you can likewise utilize the accompanying Exchange Management Shell orders:
Appears to be sufficiently basic, so what can turn out badly?
It’s not so much what can turn out badly, but rather what won’t not fill in as you may expect contingent upon how your condition is setup. The accompanying are a few contemplations that I found amid the movement of about 1TB of Exchange Databases to new LUNS.
Consider area controller replication!
When you evacuate the database duplicates or change the database way – please guarantee that you have took into consideration area controller replication to have occurred. If you don’t issue can happen amid the mount procedure on the new way.
Moreover – be aware of the replication plan particularly if your Exchange DAG hubs are in various Active Directory locales. If you are in a rush and power a space replication you should sit tight sit tight for it to finish. A replication ought to happen when every one of the accompanying advances have been performed.
- Expelling the database duplicate
- Moving the Database way
- Including the Mailbox duplicate
Additionally, on the off chance that you have a solitary system to a remote site that is encouraging space controller replication, ordinary system movement and DAG replication, be aware of what time of day you are compelling expanded transfer speed as you could convey interchanges to a pounding end.
Log replay after the DAG duplicate has been re-included
Contingent upon to what extent your databases are gotten off and how bustling your condition is, replaying logs can take a long time to finish. This will likewise be dependent on the speed of the system association which your replication organizes approaches between DAG hubs.
Carry out the progressions outside hours
This maybe one of the clearer suggestions, except if you have designed committed NIC for replication, on a devoted VLAN, on a committed system pipe to a remote data center which has your remote Exchange Servers, endeavoring to go after transfer speed on the connection with everyday movement is a “no” and will drag out the procedure.
Restarting the “MS Exchange Search” Service, after moving finished
Though not generally vital, couple of occasions where the Content Index Catalog from the past database keeps up a bolt with the “MS Exchange Search” benefit. Restarting the Service will discharge the bolt and consider the documents to be erased.
Initiating Copies after the procedure
At the point when the database way has been moved – the “MS Exchange Search” will continue creeping the database. Amid this procedure – quite possibly the duplicate won’t actuate until the point that the creep has finished on the applicable Exchange Server

When all is well, you ought to get yield like that underneath:
Try not to deal with at least two databases in the meantime!
This may sound somewhat frantic, however I would suggest that you just work on one database at any given moment on the off chance that you are moving different databases to another way. The different Services in Exchange will do bunches of various things, accordingly don’t over-burden them. Truth be told there are a few activities that can’t occur on numerous databases in the meantime.
Recommending make use of Exchange Database Recovery tool
Third-party tools like EdbMails Exchange Recovery make it a breeze to deal with the greater part of the above issues. Above everything, this apparatus can settle debased trade database records also, so there are no more worries of information misfortune.
This should be possible inside a brief timeframe, so clients can get to their letter drop at the most punctual. Hence, EdbMails Exchange Recovery is your most logical option to settle both these blunders.
