Actually after some fiddling I managed to hack the install. Installed the same version of Blesta as in my old hosted space, replete with new database. After reissuing my licence and completing the install, from phpMyAdmin dropped all tables then imported the tables and data exported from my previous install. Had to request a password reset from the portal, but I’m now in and invoicing. I spot checked about 5% of the client list, and I couldn’t find anything out of the ordinary. All my YTD reports are the same, I’m going to say everything is as it should be.
I don’t know just how true to form or best practice this is, but it works. I’ve emailed my staff and customers to let them know they’ll have to request a password reset. Which bring about a unique feature request, ability to mass reset passwords.
