So I'm still stymied with cPanel migrations. I've been promised two fixes soon, but the roadmap has yet to indicate their planned resolutions.
Rather than asking @Adam in a ticket, I'm looking for an update that might help others with cPanel migration problems, hopefully with firm dates for:
DNS zones are not migrated. Enhance will completely ignore external MX records and replace them with local values, breaking email unless you manually correct. Same applies to any other DNS records that aren't created by Enhance, they have to be created manually.
Most of the WordPress App problems are fixed with the exception of domains hosted outside of public_html (i.e. what used to be known as Addon Domains in cPanel.)
I'm still waiting for these to begin cPanel migrations, and it's difficult to plan without something more concrete, and it's a bit strange that the roadmap doesn't mention these at all.
