  • Exchange 2003 to 2013 Migration

    Hi all,

    My question is regarding Exchange 2003 to 2013 Migration.
    I understand it's a tow hop process but ,do i need to move mailboxes to exchange 2010 and then to the 2013 our it is like office 365 where i only need to install Exchange 2010 Hub/CAS and then move mailboxes to exchange 2013?

    Thanks for the help,

    you can't have Exchange 2003 and 2013 in the same Forest.
    The prreferred process seems to be do an in-place upgrade to 2010, then to 2013 from there

    what size is your userbase?

    there are some software products that reportably go direct from one to the other

      Thanks for the replay.
      So, i need to move mailboxes to Exchange 2010, decommission exchange 2003, install exchange 2013 and then migrate?

          Hi Moshiko,

          The easiest way would be to deploy Exchange 2010 in your existing environment.
          Migrate all your mailboxes and public folders
          Once everything is finished - decommission the Exchange 2003
          Deploy Exchange 2013
          Migrate everything to Exchange 2013
          Decommission 2010

          THe mixed environment mode allow everything to keep working as exchange handles all mail routing between the two environments.

            io think it depends on the size.

            if it's only 100 mailboxes, and you can migrate the data over the weekend, then Code2 or Migration wiz might be the easier way..
            depends on a whole heap of things
