Hi - it's been a few years since I did a multisite install, so need a refresher or some pointers. I'm migrating 4 sites to a WP multisite environment. All of them are currently live sites, so development needs to happen for each using a temporary sub like dev.domain.com, so I don't interfere with the live sites. Any tips on how to set this up to avoid issues once I'm ready to change the home URLs from those subs to the actual domain for each? Planning on doing the WP install at the root of the hosting plan.
Thanks in advance.
