Mac Question --Snow Leopard to Mtn Lion?

I'm thinking about upgrading my MacBook Pro to Mountain Lion but I'm wondering about the non-Apple applications I have installed? Will I have to reinstall them or do they get preserved?

I've gone from Snow Leopard -to- Lion -to- Mountain Lion without any problems.
The only way to get MLion is through the Mac App Store which I assume is available on SL, you may have to get Lion first, I don't know.
Lion and MLion don't support ANY rosetta apps and any version of Quicken seems to have a permanent problem with any version of OSX (I dont use it myself)
The new Gatekeeper security feature in MLion automatically approves all the apps you currently have installed but if it gives you any problems it can be switched off.

Thanks Paul.

According to the Apple site I can go direct from Snow Leopard to Mountain Lion. They seem to be mute on what happens to non-Apple programs. Thanks for the encouraging news. I've not used an downloaded apps so there shouldn't be anything special to worry about there.

I ran the upgrade from Lion to Mountain Lion on Friday and it did it quite seamlessly, my existing apps converted just fine. It seems like Apple's new plan is to encourage upgrading between versions as opposed to the older model of doing a wipe and clean install. In fact I'm not sure how you could do a clean install with Mountain Lion unless you get one of the apps to convert it to a USB/DVD image that you could then reboot with.

Personally I turned off the Gatekeeper, their new forced approval process for installing new apps that aren't in the App store but thats my preference.

As far as SketchUp running on Mountain Lion, I haven't bumped into anything yet and as noted elsewhere in the forum, this update for Safari/WebKit fix a bug that Apple introduced in May with an update to Safari on Lion & Snow Leopard. With Mountain Lion I no longer have black web dialog text boxes. Yaaay.

@Dave R
You can go to Mlion from snowleopard.
I don't know what apps you have there.
Most of problems may come from installers.
So.
Just install it directly on the OSX10.6.8. It will work.
Or...
when installing a fresh MLion, only then and never after, use the migration assistant. (when asked for activating a user, just chose to bring an older existing user with all apps.) . You probably used timemachine backup already, right?
Never use migration assistant after having a full running OSX. Please avoid it.
