I installed some plugins which is supported above vi version 7.4. When i open files with vi command its will show the plugin not supported with version 7.3. After that i was opened with vim command its working. Then i check the version using vi command its showing version 7.3 , in vim version is 8.x. So i checked origin vi command using which vim , which returns /usr/bin/vi.Its the softlink of another version vim. So I want    to remove old version of vim without remove installed pluginsOS:MAC 
Version conflict between vi and vim
