I've tried several times to replace the AppleLSI directory on an upgrade to 10.7.3, running server if that matters, on ESXi 5.0, and had no success. It's worked fine for me upgrading to 10.7.2 for both my Lion and Lion Server VM. My Lion VM boots and though I mount the drive from my Server VM into my regular Lion VM and copy the file, I get no success. Unfortunately I forgot to snapshot the failed on (I remembered for the regular Lion, just not the Server) and I unfortunately chose to upgrade the Server first. I may just have to migrate everything over if I can't get it working. I've tried many reboots and many attempts at the directory, but no success. Had I reversed the order of the upgrades, I could have tested the success of the regular Lion to 10.7.3, but alas.. Any idea why else it might be failing, before I clone my regular Lion VM and install server to it, then copy the data directories to replace everything? Thanks!
