Sysaid has a professional services team to handle on premise upgrades, but for those of us who don't have the budget for a cloud implementation, or to contract PS it would be nice if the upgrade documentation was up to date and linked to the "Latest Release" page so that Admins could click on it and sign in with their sysaid accounts to get it.

The upgrade instructions I was able to find are mostly okay, (despite the old version #s, and the old version of Apache):

However, they don't mention that if you use apache you may want to save the: C:\Program Files\SysAidServer\tomcat\conf\server.xml and overwrite it after the install to avoid having your chosen ports blown away. Likewise the install instructions should link to the latest version of apache since Sysaid doesn't officially support IIS. I had upgraded to 19.4 and our sites went down because our apache was old.
