According to the upgrade guide I can’t jump directly from versions (1.4.7 - 1.7.X) and need to actually step up through various versions to reach the 1.7.X version. Question is – I can’t find any way to download those previous versions. All I can find is the latest one. I’m sure its hidden in plain sight but I can’t find it.
Wow, you are still on 1.4.7? You will be in for a major upgrade bump 
Actually, we don’t publish links to older versions, so you are forgiven.
However, it is easy to figure it out as the URL is always the same, i.e.
http://cloud.razuna.com/installers/1.4.8/razuna_tomcat_1_4_8.zip,
http://cloud.razuna.com/installers/1.5/razuna_tomcat_1_5.zip, etc.
Note: Please make sure you read EACH release notes, as we have changed the
upgrade path after 1.5.
Thanks for the help Nitai.
