This week I became aware of a business unit using some outdated software. They were on version 7, and the current version is 17.
Can I upgrade it straight from 7 to 17? Nope. You can upgrade it to 8.5 in one fell swoop, but no further.
How about 8.5 to 17? Nope. The documentation says you must first upgrade to 10 before you can upgrade to "latest".
So, upgrade from 8.5 to 10? Don't be silly: you need to be on 8.18 before you can upgrade to 10.
I finally get it onto 10 and try upgrading it to 17, and it crashes. I look up the error and find a few forum posts about it. It turns out that the documentation is outdated and was written when "latest" was an earlier version. You need to upgrade to 13 before you can upgrade to 17.
I really hope this is the last step because I'm going bonkers here.
I think you're remarkably lucky that all those old software versions are available for download on the vendor's site.
I've been in similar situations where I've had to beg for copies of older software through user group forums or ringing up mates in the same line of business "do you by any chance have a copy of version x.y.z lying around?"
You'll be lucky with anything functions still work after that many upgrades... "oh you forgot to migrate the reports from template Z to the new template prior to the 8.18 update..." "we deprecated classic workflows in version 12.1" etc.
