I finally downloaded Lion last night.
The old Mac Mini Server I have is still running Snow Leopard (10.6.8). I want to set up a Win7 VirtualBox machine on it, on Mavericks, so I need to go through the upgrade chain.
A few weeks ago I bought Lion -
http://store.apple.c...6106Z/A/os-x-lion - and finally downloaded it last night. It took a while (4.7 GB). On trying to start the installation, there's a cryptic message that I need to download the Lion Server bits from the App Store. But one can't do that from SL Server. :-/
Turns out, Lion can't upgrade SL Server. I need to upgrade a non-SLS box here to Lion first, then download the Server bits there, and then put that installer on the SLS box before the Lion installer will run on SLS. (The alternative is to wipe SLS and upgrade it to Lion then install the LS bits, but I don't want to do that...)
Even with Apple, sometimes things aren't as simple as they should be...
Best of luck with your upgrade journey! You probably don't want to put it off too much longer - it's not going to get easier by waiting. Make sure you've got a good backup first!
Cheers,
Scott.
