AJM Actually I've yet to migrate the first cPanel account. I manually migrated one website from a different panel, not overly critical but one of my personal social niche sites for testing purposes.
One thing I'm aware of with current cPanel importer though: if you use mod_lsapi for PHP rather than PHP-FPM, the cPanel created php handler directive has to be removed from .htaccess. For considering full server migration from cPanel to Enhance, first remove mod_lsapi and convert to PHP-FPM or just simple CGI before the migration. (Unless of course they bake that removal into the full server importer.)
We're waiting for cPGuard support (estimated in two weeks yesterday) before doing actual cPanel migrations.
