Upgrade from < v1.6.5
Reading the upgrade instructions on http://www.couchbase.org/wiki/display/membase/Upgrading+to+Membase+1.7:
6. If your previous version was < 1.6.5 (such as 1.6.0, 1.6.1, 1.6.3), you will need to also run the following of manually creating a symbolic-link...
mkdir -p /opt/membase/1.6.1
ln -s /var/opt/membase/1.6.1/data /opt/membase/1.6.1/data
My question: why is a symbolic link to the previous version necessary? Or, am I reading this incorrectly? This seems confusing.
