[Gluster-users] upgrade gluster from old version

[Sanju Rakonde]

Hi,

I believe you can do an offline upgrade (I have never tried upgrading from
3.7 to 7.7, so there might be issues).

If you want to do a fresh install, after installing the 7.7 packages, you
can use the same old bricks to create the volumes. but you need to add
force at the end of volume create command.
