Update-ReleaseDefinition for classic release pipelines in Azure DevOps erases past releases

[sreich]

Steps to reproduce

vsteam 7.15.2

I am uncertain on how to debug and where the problem may lie, but what I am experiencing is that classic release pipeline updates via Update-ReleaseDefinition, past releases get wiped out so it looks like it has no history

I am uncertain what azdo's rules are here. But it does not seem to happen immediately. It happens after like...a day? a few days, maybe a week? Not within 24 hours.

Has anyone experienced this? I can share full scripts and try to get a minimal test case... but I would like if this is known as an issue, if I did something clearly wrong...or if it was fixed in later versions. Perhaps I am using the api wrong and missing something, as I do hand-edit (programmatically) the json, changing the fields I need and re-sending

I have observed that azdo is not the smartest when it comes to ensuring validity in their api

I just am really surprised it goes from having the past releases to...after 24 hours or so, disappearing past release histories...

Expected behavior

I expected that...the azure release pipeline updates for classic pipelines, via Update-ReleaseDefinition, would not wipe out past deployment history, that's what I'm looking to get fixed here

Actual behavior?

After the run of the script command, the pipelines' past releases (history) get erased and are no longer accessible.
