I have been migrating from old server ns9 to new server ns10.cdbsystems.com now I could NOT do the migration originally because the API login always failed https:// marius suggested editing the ispconfig.vhost and commenting out the SSL parts. did that, and I could log in and do the migration. however I would like to find out the problem so I can fix it properly! also - ns10.cdbsystems.com (which is just an A record in ns9's dns entries - should pull up the 000local site right? it does NOT come up as a secure site, and as I did on ns9 I added ns10 as a vhost under cdbsystems.com and check SSL and Letsencrypt - but still it is not showing as a secure site. so I would like to see where the bogus cert is coming from? so I can do the migration without disabling ssl! Another question I've been moving several websites, by the simple expedient of editing the A mail www records on ns9 to point to ns10 server, and do the same on ns10. indeed the sites move over. but I have to do this for every site (and I have about 100). is there some more automated way? and can I slave ns10 to ns9 so that I only have to edit the DNS records on ns9 and have them magically appear on ns10? inquiring minds and all that cdb.
