SMTP Routing for Coexistence Exchange Server and Lotus Domino RRS feed

  • Question

  • Hi,

    I have plan to do migration from Lotus Domino to Exchange Server 2013, because we can do big bang migration, we need to do migration with coexistence schema. But now i have question about the SMTP routing from external. By now, the existing mail system had mail gateway connection to Lotus Domino server. When I have my Exchange Server ready, what should I do to the SMTP routing? Can I set mail gateway to send email to both Lotus Domino and Exchange Server? Or just let the existing routing where mail gateway only send email from external to Lotus server and then it works with the Internal Relay that has been set?

    Thanks before for all your respons

    Regards,

  • Hi Julia ,

    If thats the case you can have the external mail routing setup as such until the migration is complete.

    As long as the internal relay between these email systems is set correctly then the external mail routing will function correctly.

    Regarding MX - Since the MX is pointing to mail gateway and directing mails to lotus domino you can leave it as such  till migration ois completed.

    Later  after the migration is complete you can direct mails from your mail gateway to the CAS server.

  • Hi Julia

    From Exchange 2013 the HUB server functionality is handled by transport service running on mailbox server. 

    However for reroute you need to point it to exchange 2013 CAS server since the front end transport service receives all the requests and proxies the connection to the mailbox transport service on mailbox server

    Please refer the technet article for understanding exchange 2013 transport architecture

  • Hi Julia,

    While coming to talk about the external SMTP routing 

    Currently your ISP should be receiving/delivering the external emails to the Lotus Domino Servers. You can leave the external SMTP routing as such until you introduce the Exchange server 2013 . After you install exchange 2013 servers you can point mx record as such with ISP ask them to direct it to your firewall from your firewall create a rule to direct the emails to the Exchange 2013 CAS server.

    After the above the emails from exchange can be delivered to notes user via third party integration tools until the migration is complete

    Since 2 messaging systems are entirely different (Eg: notes uses mailin database ,routing mailboxes and exchange has mailboxes and connectors) and we need to achieve a way so that these 2 different systems can interact until the migration is complete.

    You can use any Microsoft Recommended third party tools 

    1) Quest Coexistence Manager.

    2) Full Armor

    3) Binary Tree Co-Existence

    4) CASAHL Technology

    If you wish to migrate with Quest Coexistence Manager here are the prerequisite check you can check my blog for prerequisite check

    http://exchangequery.com/2014/09/12/readiness-to-migrate-lotus-notes-to-office-365-with-quest-co-existence-manager/

    Note : My blog is written for migration from notes to office 365 . But both are more or less similar. If you still need any help on this please post your comments and i will be able to assist your further.

    Good luck on your migration 

    Cheers :)

  • Hi Satish,

    Thank you so much for reply. Actually we will do the migration manually without any connector between Lotus and Exchange, I just set internal relay between these email systems so that they can send/receive mail normally. So you mean that I can let the inbound mail flow from external as the existing ? And what did you mean about pointing the mx record? because mx record is pointing to the mail gateway now. Do I need any changes of it?

    Please advise :)

  • Hi Sathish,

    Thank you so much for your reply. Now it's clear for me how to set our external SMTP routing. But I have any question about reroute mail from mail gateway to the Exchange Server, is in Exchange 2013 the server role to be pointed is CAS Server not the Mailbox Server? Doesn't the hub transport role from previous Exchange version is adopted by Mailbox Server in Exchange Server 2013?

    Please advise :)

  • Recently I found a powerful tool which I tested in my environment is Bitacube Lotus Notes to Office 365 migration tool

    https://www.bitacube.com/lotus-notes-to-office-365-migration.html

    It has good capacity to migrate Lotus Notes to Office 365, live exchange, PST, eml, msg, as well as HTML.

    Though I recommend to have a free trial first if it suits to your environment.
