Troubleshooting/Logging Exchange 2010 SP3 RU6 issue

Troubleshooting Exchange 2010 SP3 RU6 issue
Run following from the command line

Exchange<2010>-<KB2936871>-x64-en.msp /lxv* <E>:\<RU6InstallLog.log>

Eg. 2936871 is the number
Exchange2010-KB2936871-x64-en.msp /lxv* E:\RU6InstallLog.log


Reference from
https://technet.microsoft.com/en-us/library/ff772434%28v=exchg.80%29.aspx?f=255&MSPPError=-2147217396

and
https://blogs.technet.microsoft.com/exchange/2008/07/08/exchange-2007-managed-services-might-time-out-during-certificate-revocation-checks/

Resolution: 
Tried running many times, revoke Security check from the IE and tried opening Microsoft website but site was not opening, it kept circling without any page response/error message.
Then ran command from the "Command Prompt"

c:\>Exchange2010-KB2936871-x64-en.msp /lxv* E:\RU6InstallLog.log

 /lxv* is a switch and file name can be change.
One thing you will notice that after adding swtich in the above RU6 Installation will go slow and finally i was able to resolve the issue

Resolution in the same series
event Id 2280 because, re-installed Exchange 2010 Hub role on a different Location so it while installing first time, it registers its custom modules with IIS and for this it makes entries in the IIS root config file i.e. applicationHost.config at this location 
C:\Windows\System32\inetsrv\config. 

These enties are made under the <globalmodules> section. 
You will see one such entry for kerbauth.dll.
  <add name="kerbauth" image="C:\Program Files\Microsoft\Exchange Server\V14\Bin\kerbauth.dll" />

so replace the location of the current installation file at "Kerbauth" and save the file.

DataBase Portability

Exchange 2010
-------------------
Moving Mailboxes between DAG (between DAG havn't tested Yet)

1.  Mailboxes will be offline, since we have to dismount the Database

Sequence of tasks that need to take place:
  • Dismount mailbox database on old server
  • Run eseutil /MH NAME.edb to confirm you have a clean shutdown.
  • Create new mailbox store on New Exchange server and mount it.
  • Dismount the new mailbox store
  • Manually copy the old database to the new mailbox store database location (make sure it is the same name)
  • Run the following command on new server Set-MailboxDatabase DBNAME -AllowFileRestore:$true
  • Delete the transaction log files and checkpoint files for that database.
  • Mount the store.
  • Finally modify user account settings so user access points to the new mailbox server
    Get-Mailbox -Database OLD_DB | where {$_ObjectClass -NotMatch '(SystemAttendantMailbox|ExOleDbSystemMailbox)'} | Set-Mailbox -Database NEW_DB
Referenced from
http://serverfault.com/questions/463104/fastest-way-to-migrate-exchange-2010-mailboxes-to-another-exchange-2010-server-i

2.Create the databases on the new exchange server and issue mailbox moves to the new database. You can batch it up pretty quickly though in powershell.
