Hi Experts,

I am in the process to upgrade from EXCH2007 to 2013.
About the Schema update , the domain and forest update I am not sure.
Can I do the POWERSHELL commands again  to check it ?

from PowerShell, with Run As Admin type:

[PS] C:\> "Exchange Schema Version = " + ([ADSI]("LDAP://CN=ms-Exch-Schema-Version-Pt," + ([ADSI]"LDAP://RootDSE").schemaNamingContext)).rangeUpper

Then take a look at this site, to see on what version you are:

The range is ok.

if you have already run those commands, then there is no reason to run them again.
You can just run installation.

I haven't run it more then once, so not sure. Don't think it will do any problem, since I do know that sometime, when you get into problem with arbitration mailboxes, it is required to run those commands again.
