Upgrading HBase 0.98.7

[Akmal Abbasov]

Hi all,
I’m planing to upgrade my HBase. Currently it’s hbase-0.98.7-hadoop2. I was 
wondering can I upgrade directly to current stable version, which is 1.1.2?
Moreover, I can tolerate downtime, so in this case upgrade process will include,
a. Installation of the new version 
b. Distribution of configurations
c. Change links to reference to a new version
d. $HBASE_HOME/bin/hbase upgrade
e. Start upgraded cluster
Is this the all required steps which should be done?
Thank you.
