No worries! I was complacent unfortunately, the 25k SQ were prompt, as were the Star Alliance points, but they insisted I take Gold (I tried arguing the vague T&Cs, but ultimately the points were awarded on the basis that I had SQ Gold, which I no longer did). Only plus is that while making my case I switched to AC, so got AC 50k status until 31/12/2027. Hopefully I can therefore accurately declare Gold next year!
I had actual SQ Gold when I last held this card, so didn't consider it being an issue. Not an issue with the AC offer though, the terms were clear that you have to receive Star Gold to be eligible for the 30k Aeroplan points (SQ offer was qualifying if you took points in lieu of Gold, so it was the standard terms which I tripped myself up on).
Hopefully anyone else going the same way can get in there and tip the points into their preferred FF program in good time (I had about 4 weeks in which I could have done it too

- oh well, live and learn!).
When you qualify, you'll get an email saying you've got 14 days to select your preferred airline, at that point (14 days later) they'll process it and award the points/status (as appropriate). The bonus SQ miles will be directly credited by SQ to your KrisFlyer account, separately to this.
