Hi Peter, I upgraded straight from Snow Leopard 10.6.8 to El Capitan 10.11.6 on two IMacs and a laptop. I am currently writing this on the older iMac - a mid 2007 24" Model identifier 7.1 - so older than your machine -though I do have a bit more RAM fitted - 6GB (which is the max for this model).
Regarding your software you would need to check all your apps to see what versions of each are compatible with El Capitan but: - Regarding CS3 - no personal experience but check out this discussion (sounds like you should be OK?) https://community.adobe.com/t5/download-install/cs3-on-mac-os-x-el-capitan-10-11-5/td-p/9526794?page=1 - Regarding Office - I was running Office 2004 - so had to upgrade and decided to got the Office 365 subscription (see some of my previous posts for reasons) - One problem I found was that with some Office 2004 Word & Excel docs - where I had carefully formatted to give a specific pdf format - opening in the latest Office would change the formatting slightly which was annoying so I ended up running the offending docs through Office 2011 first. Just a minute - this is all sounding very familiar - I think you asked the same question last year which I answered here!! : https://www.mail-archive.com/wamug@wamug.org.au/msg82377.html Don't forget the backups!!
