Waiting to pull off Houdini till the last minute is unnecessary especially considering they knew they will have to do it anyway at some point. So weather they spend the money 20 years before, raise no suspicions, keep your secret a secret and keep all your people alive or wait until the last minute, blow your cover, kill a bunch of your people and then destroy all the evidence which is evidence all by itself by the way is possibly the dumbest way to do things.
They probably needed some pulling the strings on Mesa to keep the transtellars playing their stalking goat role, and keeping them from doing something to disrupt the time table.
They may even have wanted some people tied into the genetic modification efforts, because the genetic slave trade let them 'stress test' modifications to see how they fared in more varied and rougher conditions than on Darius. (And you don't risk alienating your friendly Darius slaves by killing off their kids in high risk experiments).
But there was a lot of work in the research centers that should have been transferred long before. They might have needed as many as a couple thousand people on Mesa to use it as they wanted, but it seems they had multiple tens of thousands - most of which appear to have no truly compelling reason to still be there.
There'd have been some disruption as you moved people over, because it wouldn't be a 1-shot mass migration. But with a couple centuries to go in the master plan you can afford disruption of research to get better security.
I'd say when prolong because available that should have spurred them to start moving people - prolong means the new people are going to be around for a long time as if you move good prpospects while they're still young enough to get prolong it'll probably be before they settle down and raise a family and about the time they'd be likely to move away for a new job. So fairly easy to cover slipping them off to Darius. But that lets you let many of the current staff retire and die off of natural causes but doesn't lock you in to multi-century extended families the new prolonged workers will eventually have, when the time comes to pull the Houdini trigger.
Think how deep and intertwined the family structures might be given another century when you might have 1st gen prolong great, great, great, great grandparents still in the prime of their life and interacting with all the follow-on generations. Moving many of those people would be way more noticeable - but if you don't (and don't kill them) they're a potential security threat (if Mesa is captured) for at least another century. Better, to my mind, to sidestep that complication and send all but the most dedicated and necessary prolong recipients directly off to Darius where their tendency to form families doesn't make Houdini any more complicated.
