When we purchased the suite of tools, each tool had a download that specified "standalone". Is there a particular file we should use when getting the upgrades (WAR or TAR)? Also, is it recommended to upgrade by each version vs jumping? For instance we have Bamboo 3.4.3. is it OK to just get the latest version or do I need to get each version in between 3.4.3 and the latest version of 4.2?
