So our illustrious platform guardians decided to push the big red 'upgrade' button and now our entire custom risk rule framework looks like a toddler's abstract art project. Classic.
We had a beautiful, if slightly Frankensteinian, collection of risk rules built up over years. Correlations, threshold-based alerts, the works. Post-upgrade to ES 8.x? Inert. The risk index is populated, but the rules themselves might as well be written in Sanskrit for all the good they're doing. The logs are… unhelpfully cryptic. "Execution failed." Thanks, that's illuminating.
I'm curious if this is a universal rite of passage or if we just won the reverse lottery. Specifically:
* Did the underlying risk rule syntax or logic engine change that much? Our rules were built in the 7.x UI, not raw SPL config files.
* Is there a known graveyard of deprecated functions or a new mandatory field mapping we all missed in the release notes buried under 500 pages of "enhanced synergy"?
* Or is this a permissions/ownership migration issue where the new version just decided our old rules don't have the right to exist?
Asking for a friend whose SOC is currently operating on vibes and prayer. Just stirring the pot
But what about the edge case?
"Execution failed." Classic. They spent three years on a rewrite and that's the best they could do.
Yes, it's a rite of passage. The risk rules engine got a "streamlining". Your old UI-built rules are probably calling functions that got renamed or removed. Check for any conditional logic using stats or eval commands from the 7.x era - the mapping syntax changed for a bunch of internal fields.
The release notes called it a "migration path". I call it a land mine. You're not on vibes and prayer, you're on grep and trial-by-error.

Your "Frankensteinian" collection is exactly the problem. The UI hid the monster, but now you have to look at the stitches. The 7.x UI wrote a lot of SPL2 under the hood that the 8.x engine simply rejects.
> Is there a known graveyard of deprecated functions
Yes, but it's not just functions. The entire data model for how rules reference the risk index shifted. Your old rules are likely trying to access fields like `risk_score` or `risk_object` with the old dotted notation. That mapping got flattened. You'll need to export those UI rules, translate the SPL, and recreate them. It's a manual rebuild, not a migration.
Permissions might bite you too, but that's a secondary symptom. The primary issue is your rules are speaking 7.x dialect to an 8.x parser. The logs are cryptic because the engine doesn't recognize the foundational commands anymore. Start by checking the search string of one broken rule; you'll see the antique syntax.
