Decomission old Lotus Notes server

The company I am working for aquired another company in the past. All of their domain was merged into our domain (prior to my employment here).

All of the services off the merged companies domain have been migrated into our domain. All Except for an old Lotus Notes server (Which I know nothing about Lotus notes).

I would like to raise our domain level to 2008 R2 and decomission the 2003 DC's.
Currently there are 5 DC's :
* Svr 2003 - PDC
* Svr 2003 - secondary 2003 DC
* Svr 2003 - DC drom the merged domain
* Svr 2008 R2 - Primary 2008 R2 DC
* Svr 2008 R2 - Secondary 2008 R2 DC.

The problem I have is that if I power off the DC from the merged domain (3rd in the list above), Lotus notes stops working. And obviously I cannot raise my domain level without decomissioning the 2003 DCs.

The DC from the merged domain doesn't actually host the merged domain name. It no longer exists. It only hosts the current domain name. The only reference to the old domain name is in DNS forward lookup zone.

I assume the only thing stopping me from decommissioning the merged domain DC is that I would need to change references to hostnames etc on the Lotus notes server.

However, as mentioned. I have no idea how Lotus notes works.

Any help would be greatly appreciated. Ideally I would like to be able to export all mailboxes off Lotus Notes and import into Exchange 2010.

What is the domino version you have? You want to replace it by Ecchange 2010, right?

And what is the number of mailboxes etc. Maybe there is not so automatic process for you.

Hi:

What do u meant " stop working of lotus notes", could u explain how it not work, AD and IBM domino actually separate no affect on each other except they integrate single sign on . Just stop the single sign on in client may achive.

Or i think your domino maybe DC or members service right ? just try demote to workgroup server and test again.

May I suggest you spend a few days at the merged companies, so they can tell you what their Lotus environment does exactly? There's nothing worse for the users at the other company than to be told that "the decision has been made to ..." while never having been involved in the decision making process.

If it's only mail, you can migrate to Exchange (although I'd prefer to see you migrate off Exchange ;-)). If they use other databases, you'd better go for a coexistence option between Notes and Exchange, as you probably already have.

As for the Notes server: it can even be installed on Linux, there is little tie-in with the O/S. There are simple (manual) procedures to back up a Lotus Domino server (clients are called Notes clients) and restore it on a new server. Do you/they have the installation media?

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

>> The domino server name (within Domino) cannot be easily changed. However as long as you retain the Domino server name and simply update DNS , you can move the server to a new host or change it's IP address quite easily.

>> Depending on the number of mailboxes to migrate you may want to look at some third party tools such as www.binarytree.com or just use the Microsoft migration wizard supplied with Exchange.

Thanks for the answers people. The Mailboxes have all been migrated.

However there are also a few databases that one of our Legacy apps uses.
I better contact the vendor of the app for assistance migrating that to SQL.

As I said (but I may not have been explicit enough): "if they use other [types of] databases, you'd better go for a coexistence option between Notes and Exchange".
Meaning: it is almost impossible for a non-Notes expert to migrate non-mail databases with the flick of a switch. It might cost you a bundle. Often, the cheapest solution is to keep the Domino server running, it happens all the time...
