I made some tests with MongoDB 2.1 (unstable debian package). I want to test the code with 2.0 stable to see the speed difference.

Can I simply uninstall mongoDB 2.1 and reinstall 2.0 without caring about the data ?

Thanks

    Yes, you can use the data files created in 2.1 with 2.0. You could also download a suitable Linux version from [mongodb.org/downloads](http://www.mongodb.org/downloads) and install this in a separate directory if you want to run a comparison of both versions. – Stennie Aug 09 '12 at 10:04

@Stennie replied the question with his comment. I tried and it worked. On the mopngoDB website, the best is to download the legacy-static witch is very usefull for version testing. Be sure to put the right data path to mongod ;-)
