Q: Upgrade from OS X 10.7.5 Lion to 10.8.5 Mountain Lion
Want to upgrade from OS X 10.7.5 Lion to 10.8.5 Mountain Lion (not a clean install).
Can I make a copy of the downloaded Installer Package or will it automatically start installing as soon as it is downloaded?
Should Time Machine be turned Off while the installation is running?
Really appreciate your help and any tips you have to offer. Thanks!
MacBook Pro (15-inch Late 2011), Mac OS X (10.7.5)

Summary & Conclusion:
OSX Mountain Lion was downloaded from the App Store (Apple sent it as Version 10.8.5 = no updates required).
Installation went smoothly and without any glitches.
MS Office for Mac 2011 was then updated.
The MS Database was then rebuilt with MS Database Utility.
Mac HD Permissions were checked & repaired (mostly iTunes Permissions) with Disk Utility.
FireFox 45.4 ESR was downloaded, installed & set-up.
Everything is running great on my MacBook Pro and I once again have secure access to online banking!
Thanks to each of you for all of your help!!!
