![]() ![]() What do you have in your 10.7 that you can't install afterwards on the VM? If you think about it, you could have a fresh start with a new VM, without all the garbage that gets accumulated over the years. Leftovers: 1 backup HD, in case something goes wrong. Cost: 1 new HD + 1 USB3 HD case (if you don't have one). You'll need the external USB3 HD case, *and* to make a USB pass-through of the case to the guest. When the time comes to "restore" your user data/applications, pick "An external HD" and connect the HD that you retired. Install a 10.7 VM in your shiny-new host.Do not worry about apps that are not 10.7 compatible anymore, and do not install apps that have gotten a 10.13-only upgrade (e.g. Bonus: you get to keep only the compatible applications. You'll need an external USB3 HD case for that. Install the 10.13 on the new HD, then when the time comes to "restore" your user data/applications, pick "An external HD" and connect the HD that you retired.Then remove the old HD from the iMac and replace it with the new one, your new host! It has two advantages: a) I get a bigger one, and b) I "retire" the old one as is, as an archive, a backup. I would get myself a new HD, that's what I always do when I do a major upgrade. ![]() What do you have in your 10.7 that you can't install afterwards on the VM?

But I would strongly prefer a VM solution. Worst case scenario, I could just use CCC to clone the internal hard drive to an external one, then upgrade the internal drive to High Sierra, and boot Lion from the external drive when necessary. But the problem remains, how to P2V the Lion installation on the internal hard drive? Would something like Carbon Copy Cloner, or Super Duper, or even Parallels create a disk image that could be imported as a Virtualbox disk? How do I do that? I want to upgrade to High Sierra, but I have some old apps that won't run under HS, so I want to P2V my old Lion install so I can run it as a VM when I need to use those apps.įWIW, I have successfully installed HS on an external hard disk and can boot from it. ![]()
