WordPress multisite questions
I have 4 sites all using a separate WordPress installation, my main domain is www.mikeandshar.com , My Addon sites are www.hartfamilyhistory.com , www.cafinity.com , and www.rainsonfamilytree.com
I would like to use WordPress multisite and manage all from my main domain. Before I do this I have a couple of questions.
1. Will people now accessing my Addon sites have to enter a different url: for example to access hartfamilyhistory.com, will they now have to enter www.hartfamilyhistory.mikeandshar.com
2. Will the links in my current Addon sites need to be redirected?
3. What happens to the databases for my existing sites?
