In this part 4 of the move operation, we will tackle the modifications we have to do on our ISA 2006 server, to make SMTP traffic and OWA work towards our newly installed Exchange 2007 server in the network.
A lot of these steps are already documented in more detail in a previous post of mine (how to publish Exchange 2007 OWA using ISA 2006), so feel free to take a look:
The necessary steps will be mentioned here again to keep the overview of the steps we needed to do during the complete move operation. For details on every step listed here, refer to the previous post above.
1) Create a new Certificate request file using the “new-exchangecertificate” cmdlet
2) Upload the request to your internal CA or use an official one (eg. Comodo, Verisign, Thawte,…)
3) Import the certificate on the Exchange server, and link it to the IIS, POP and IMAP Services
4) Export the SSL certificate from within the Certificate MMC on the Exchange Server, and copy this file over to the ISA box; import the certificate on your ISA server.
5) Modify the host file on the ISA box, to make sure the OWA URL (eg. Webmail.pdtit.be) is referring to the IP-address of the new Exchange server, or enter the IP-address directly in the wizard
6) Modify the existing SMTP Publishing rule, where the target IP-address should refer to the new Exchange Server
