Reason why this is critical - incremental transfers from cPanel/Plesk to Enhance. This will explode Enhance subscriptions allowing so many more to migrate from Webpros => Enhance.
A very common scenario:
- Dozens if not hundreds of websites pointing to an existing cPanel server via A-record (lets call this IP address X)
- We migrate some sites to test out the websites on our new Enhance server (let's call this IP address Y)
- While testing, we set the DNS zones for these 10 domains to have IP address Y, so it hops traffic over to the new server.
- Rest of websites, not migrated yet, are running on the old cPanel server on IP X, still.
- We are satisfied with the results, and decide to migrate the other 290 websites overnight.
- We cannot possibly talk to hundreds of clients and get them to log into GoDaddy one evening to set the A-records to IP address Y.
- After migrating them all, we move the IP address X from the old server to the new server (move Elastic IP from one network device to another on AWS Console)
- The 10 tester websites that were operating on IP address Y are now configured to work with IP X instead.
- Clients did not need to touch their Godaddy dashboards, and we kept all websites on the original IP X, while Y was used temporarily only.
- We remove IP Y because we like saving a few bucks a month (I know it's not a lot, but Elastic IPs cost $$$).
This whole time, if the Enhance server can be configured to receive requests and serve website for both IP X and IP Y would be immensely helpful for testing purposes.
Because our websites constantly get new data syncs, we cannot test websites individually by spoofing our own host files only. We as soon as we move a few sites to the new server, it has to keep its data updated every 2 hrs or so via an API process.
This is one of the big bottlenecks I saw when it comes to mass migration of hundreds of websites. We cannot commit to moving all at once - has to be incremental for us to test all API functions, database stuff, compatibility of our websites talking to each other.. while we are not on Wordpress, I'm sure a lot of people want to make sure their Wordpress plugins, SMTP ports for Sendgrid etc. are all working etc. before fully migrating, and cannot possibly coordinate with LOTS of clients to update their DNS in one go..
