After a bit of back and forth with the people in charge of this, here is the final reply.
Was I misinformed by
@Dan about them counting stays from both programs for this?
I have been asking for a source for the “conssesions” from the first time Dan posted about it.
(Hardly any chatter on it from their source on FT too)
The reply:
In order for Members to obtain Lifetime Elite Status per our new Loyalty program requirement, the Member must meet the below Lifetime Elite Status Criteria.
Lifetime Silver Elite: 250 Qualifying Nights + 5 Years as Silver Elite, Gold Elite or Platinum Elite
Lifetime Gold Elite: 400 Qualifying Nights + 7 Years as Gold Elite or Platinum Elite
Lifetime Platinum Elite: 600 Qualifying Nights + 10 Years as Platinum Elite
***Lifetime Platinum Premier Elite: 750 Qualifying Nights + 10 Years as Platinum Elite
If you obtain Lifetime Elite status based on the Legacy programs (SPG or Marriott Rewards), kindly note that the Nights has to be achieved from stay at the individual program hotel Brands. For example of earning Lifetime Elite status per the Legacy SPG program requirement, the 250 Nights has to be from stay at SPG hotel brands and 5 years on Gold or higher.
