We have Ex 2010 & Ex 2013 servers in a single domain.
Exchange 2010 standalone server with all the roles installed.
Exchange 2013 are 5 nos. 3nos are Mailbox & 2nos are CAS.
I have migrated all the User Mailboxes form Ex 2010 to Ex 2013. (Note:We are going to DECOMMISSION the Ex 2010)
I have one Discoverysearchmailbox, which is in 2010.
There is no Discoverysearchmailbox in Ex 2013.
Note:You can’t use the Exchange admin center (EAC) because discovery mailboxes aren’t displayed in the EAC.
If i dont have Discoverysearchmailbox in 2013,then do i need to move from 2010 to the 2013 or i need to create a new\fresh discoverysearchmailbox in 2013 exchange servers.We are going to decommissioning the exchange 2010 server.
As i mentioned,we have 5 exchange servers in my topology,the ex 2013 servers will have any discoverysearchmailboxes by DEFAULT?
What about the Arbitration mailboxes. Should i move the Arbitration mailboxes from Ex 2010 to Ex 2013.Is it mandatory>
