[Gluster-users] upgrade gluster from old version

[liu zhijing]

hi everyone!
I found It is hard to upgrade  from a gluster version from 3.7.6 to 7.7,so I remove all the install package and delete all config file except the brick, and I resinstall the glusterfs 7.7, then reconfig the same volume name but use a temp brick.after everything is ok ,then i stop the volume and replace the old brick , change the brick volume id as the new volume id , at last  start the volume successfully.
What I want to know is  if this is the right way to upgrade .
