Our server migration project — getting dozens of websites off an old server, was completed in August. Ten troublesome websites (running outdated PHP and old xCarts and such) were put onto an intermediate server, a virtual machine running an old version of CentOS. We’ve been updating those sites one at a time. Two have already been updated and moved to our modern Ubuntu 18 server box. The rest will be moving over as the code for them is re-written and updated.
I realized we’ve been hosting some of the same websites for 20 years! We’ve updated them several times over the years, but still…. that’s a long relationship!
