If MongoDB 2 should be your "default" Mongo DB, install mongodb first and rename everything to *3 (instead of *2). MongoDB 3 will be installed with the default file and folder names then. Modify /usr/local/Cellar/mongodb26/2.6.12/ to reflect the changes above (log directories and config file).Modify /usr/local/etc/nf to reflect the changes above (path and dbpath) and a different port in the net section (e.g.Rename /usr/local/var/log/mongodb to /usr/local/var/log/mongodb2.Rename /usr/local/var/mongodb to /usr/local/var/mongodb2.Rename /usr/local/etc/nf to /usr/local/etc/nf.bsondump to bsondump2, mongo to mongo2 etc) Rename all fourteen "mongodb26" soft links in /usr/local/bin (e.g.Install mongodb 2.6.12 with brew install mongodb26.

Is it possible to install both mongodb 2.6 and 3.2 on the same Mac? I’ve been using mongodb 3.2 (Installed with homebrew) for a while but needed to install 2.6 to support an older project.
