If you are currently using the hosted and managed versions of Watch My Domains SED v3, you should consider contacting us to schedule an upgrade to the current v4.
Upgrading will be painless because you will have access to the old and new versions and we will take down the old installation only after you have confirmed that it is okay to do so.
The new installation will have all your domains, custom data columns (plus data) and your categories intact. You will need to recreate your users and assign access rights. You will also need to configure the reports and scheduled emails. This is not complicated because you can do this easily from the user interface.
Before scheduling an upgrade you should fix a date and time after which you will stop making any additions to your current version 3 installation. Then contact us for setting up the new version.
