We have an EV SSL certificate on one site which currently links through to a number of other independent domains using separate instances of Wordpress but not using SSL.
I understand from your article on SSL Domain Mapping that if I set up the MultiSite using subfolders the EV SSL should work fine if I make the main site a MultiSite and map those other domains to it - is that correct?
The domains with and without SSL are all on the same VDS and therefore have the same IP address and nameservers.
I am trying to figure out the best order of work to avoid downtime as I will be messing around with live sites.
To complicate things still further, there is a live Magento shop (the main reason for the EV SSL) in a subfolder of the main domain with the EV SSL certificate that I need to maintain as live, and am concerned that this may be affected by the changeover to multisite. I guess there should be something added to the .htaccess but need to be sure. Is it possible to exclude the /shop folder?
Will setting up the EV SSL site as a Multisite compromise the rules governing the use of that type of certificate?
I also need to understand the SEO implications of doing this before we go ahead.
I feel I need a more comprehensive guide than the one on your How to Use SSL and HTTPS with WordPress page.
Sorry for the long ticket and multiple questions but this is a big investment for us and we don't want to risk breaking the existing sites or falling foul of PayPal and/or Trustwave rules in the process.
We tried doing this several years ago with no success so cancelled our WPMUDEV subscription, but have decided to give it one more go as things seem to have moved forward with the plugin.
Hoping you can help.
