If you do that in the app store (ios or android), prepare to get thousands of 1-star reviews for your old version from people who believe they are entitled to updates for their lifetime.
I've seen it upfront two times in the playstore, where apps I liked released a new version. I was eager to buy the new version but the new/updated reviews for the old ones were ruthless. One app had to give the new version for free. The other had to promise to keep updating the old version too. The first team just gave up on both apps. The second team (one developer actually) continued but slowly toned down his efforts, going into essentially maintenance mode.

As I user I've had the opposite problem: developers who radically change an app that was perfect. I have no way to revert to the older version I preferred. If the developer had created a new app, I could have stayed on the old one. It's unfortunate most other users want unlimited updates. Paid upgrades and version selection remains an unsolved problem.
Yeah. I disable auto updating for this reason on my phone. I've had a number of apps change up their functionality on me or add obtrusive ads and I can't go back to what once worked just fine for my needs.
If the software is actually useful people will complain but ultimately purchase it. Problem is, almost all software is only really useful to a select few and just kind of nice to have for everyone else.
Buying Office 2015 only gets you that version.
If you want Office 2017, it's not an 'update' per se unless they generously offer it to you, but rather an entirely new piece of software.
