We currently have epo 4.0 in our environment hosted on a physical/single server running Windows 2003 sp2. We plan to upgrade to v4.5. The database is hosted on a seperate box.
It would be great if someone could share the best practices/checklist for the before we go ahead with the upgrade. We'll ofcourse backup the database before proceeding with the upgrade. If anyone has been through this and would like to share the experience, caveats it will be greatly appreciated.
