Logic Pro 9 help w Logic versions installed....


So my original install on the Mac Book Pro I use with Logic was a full Logic Pro 8 install. I have continued to upgrade so now I am up to date w 9.1.5 Here's my issue...looking into my application folder the older versions of Logic 8 and a earlier version of Logic 9 seem to be separate applications on my MBPro....

Is it ok to uninstall or trash these?? If so what is best way to go about it?
