  • Moving exch 2k3 to a new server... Help

    Good afternoon all,

    I am needing to move our exchange 2k3 server to new hardware.

    Is the best/most simple way to do this, just building out the new server with the same name/IP's and setting then simply restoring a backup of the information store?

    Thanks for the help guys.... and gals.

    -Jon

    This is the process I use. It works like charm if you follow the instructions.

      Not a fan of the backup restore method. The risk is too high and completely unnecessary. I actually refuse to do it because of the risk.
      Swing migration is risk free, zero downtime and at no point is the data at risk.

        This looks good, only downside is that all of the users connect via RPC over HTTP.

        I guess once all the mailboxes are moved, Ill just have to confiure the RPC and MX/DNS records right after the move so they can connect?

        Will have to change anything under the outlook client? IE server name? Since they all use RPC over http?

        Thanks for all the help guys!

          With all due respect to Simon, who is the resident Exchange expert: The procedure outlined in the article I linked to is straight from Microsoft and as such is fully supported by them. IMHO, it's the fastest and least error prone method of moving Exchange to new hardware while keeping the same server name. I've used it many times and have never had the process fail. There's no configuration to be done, no moving of mailboxes, no settings to change, no PF replication to worry about, etc., etc.

            Hummmm...


            Joe- Can I still use your instructions, even if I do want to change the server name?

              No. If you want to change the server name then use Simon's procedure.

              Also, moving Exchange to a new server and using a new name will mean reconfiguring all of your Outlook clients. I don't beleive that RPC over HTTP has a mechanism for rehoming Outlook to the new server.

                Could I just do this:

                1st off my current exch server sits on our only DC.

                Bring the new server up with a fresh OS install, run DCpromp, let AD replicate.
                Then, install exchange, then apply any updates nessary, run the RPC wizard tool.
                Configure the new server with a new name the same settings as the old one is configured with.

                Restore the lastest information store backup, reconfigure the users outlook clients with the new server name.

                Finally shut down old server and see if it works?

                Would that work?

                  Oh, the machine is also the DC? That's a whole other bag of worms.

                  Is it the case that you want to remove the old server completely and permanently?

                    Wonderfull, LOL.

                    yea, we basicly have one server. Our exchange/DC.

                    So after I have configured the new exchange server/DC, can I simply run dcpromo and remove the old DC?

                    My IT skills are a little rusty, I got an MCSA serveral years ago, and about 4 years ago made a move out of IT into ERP consulting/sales.

                    Thanks for all the help!

                      Its fine as long as

                      a. Your backups are fine
                      b. You can afford the downtime
                      c. You can afford the downtime if the backups do not work.

                      It puts your data at unnecessary risk. The key word there is unnecessary.
                      I have said this before - I work on the least risk or worst case scenario.
                      For me to use backup restore I have to plan for
                      - the hardware to fail after the process has started
                      - the backup to bad
                      - the database on the original server to be corrupt.

                      What do I then? There are only so many backups I can have.

                      I do migrations where the cost of downtime is measured in $10,000s per hour, and have never had more than 2 minutes downtime in any migration. The swing migration is completely risk free, at no point are you in a position where you cannot back out. While it maybe supported by Microsoft, it doesn't mean it is the best solution.

                      I also see the point about RPC over HTTPS being used. That doesn't matter. As long as you have used a generic name for the SSL certificate, rather than the server's real name, then the change is completely transparent to the users. If you have used the server's real name then that causes a little more headache but can be worked around easily enough.

                      With the machine being a domain controller, that certainly complicates matters. A swing migration would be the best option then. Make the new machine a DC, then install Exchange. Once the migration is complete you must remove Exchange before running DCPROMO to remove it.

                        Crap, I dont remember about the SSL cert, it was a few years ago that I implemented this exchange configuration.

                        If I did use the real server name will I have to purchase a new SSL cert?


                        Thanks for all the info guys.

                          Depends how old the certificate is. If the certificate doesn't have long to run, then I would be considering replacing it. When you can purchase trusted If it was using the server's real name then you could look at changing it to a virtual name. While that will mean some impact on the users this time round, at some point you would need to make the change to a generic name, particularly if things grow.

                          The problem with a real server name is getting things to work correctly during the migration period, and then confused users ongoing.

                            Alright guys, Im back!

                            OK, I have just installed a second exchange server with a different name.

                            I was able to connect a test user I created, and I could send/receive email to and from the outside world not using RPC. I could not connect to our current OWA though?
                            I also have replicated the public folder/systems folders as well.

                            Should I go ahead and configure RPC over HTTP now or do I need to wait until I take down my "old" current exchange server?

                            I do have DNS forward look ups on my old exchange server, Im guessing I should move those over as well?

                            Keep in mind my "new" exchange server is not only replacing my old email server but my only DC as well.

                            So should my next steps be, put old servers IP address in the new server, shut down old server and see if I can connect a "test" user to the new server using RPC over HTTP?
                            Tonight of course so users have no downtime?

                            Thanks for all the help guys!
