MailServer Migration
Description:
We needed to migrate the email server running MailEnable to Server2012.
To Resolve:
-
Follow the steps on Create A New VM.
-
Once the VM is created, we need to enable the IIS role (leave defaults) and install the email server software.
-
After installation, we need to export the “mailboxes” and “groups” from the old server.
- This can be tricky, but you need to export as a text file. Then copy into Excel/Word until you get it to “username,password”
-
Open up MailEnable on the new server and select “import users” => point to that file => select the option to select a custom mailbox size, we did “500000”.
-
This will populate all the users. Now to import the groups. We did these manually as there isn’t very many.
-
Now we need to enable TLS. To do this, we need to add an SSL Certificate.
- Launch IIS Manager => Go to ServerName => Server Certificates- Create a Certificate Request. Fill out the request.
- Login to Digicert => Request a duplicate (we already had one for the Barracuda device).
- They will send an email. Save the certificate to a shared folder.
- Go back into IIS => Server Certificates => Completed Certificate Request => Use friendly name: example.net / Save to Personal cert store
- Now go to IIS => Sites => MailEnable Protocols => Bindings => Add => HTTPS for port 443. Cert should be the cert we created.
- Now go to IIS => Sites => Default Site => Bindings => Add => HTTPS => Port 443 => Cert we just created.
- Make sure ports 80 and 443 are being forwarded from the firewall to the web server.
-
Lastly, you just point the new Mail Server to the old mail server’s IP address and make sure all configurations are the same inside the options.
