This topic is part of research I am doing to help determine the best solution for my client’s needs.
Client’s flagship Joomla 3.9.12 site on a Plesk server: OURDOMAIN.ORG
Client’s Joomla 3.9.12 Multisite on a cPanel/WHM server: OURDOMAIN.NET
Question: If we migrate the OURDOMAIN.NET multisite platform over to the same Plesk server as OURDOMAIN.ORG, I’m told that there is a way to configure the Joomla Multisites system to resolve to the SLAVE1.OURDOMAIN.ORG urls. I’m wondering whether a wildcard SSL for *.OURDOMAIN.ORG would secure the slave URLs which are technically under another Plesk subscription — assuming of course, that they resolve? Would it trigger the browser lock icon?
We could of course, extract all of the slave sites out of the multisite platform and make them true subdomains, but that is looking like it would be quite expensive.
