Upgrade offer?

Sorry if it has been asked before.

Just recently got my gold in April and have spent 10k so far.

I had a look at plat and I am interested in upgrading.

I’ve seen people saying that if they ask for an upgrade during an elevated season, the upgrade bonus tends to be better.

Should I wait to upgrade at my renewal date or the “Autumn” seasonal elevated bonus offers or just message cs now.

Or at 2 months account age, it is way too soon for them to even consider it. Thanks
