I expect that it will be better than the previous PSS cutover but given the trauma inflicted for me -- who existed essentially entirely in the pmCO world and did a fraction of the travel I do today (I think I struggled to hit Silver that year if I am recalling correctly) if it's 1/10th as bad as then it will be bad in an epic way -- I had flights appearing, disappearing, being double credited, being improperly credited, etc. for weeks... and theoretically, at least, I wasn't even changing systems.
I get being pessimistic on it this time, however, I imagine comparing these two is Lada vs. Bentley. Never mind the completely different approach to how modern infrastructure works, with microservices, isolation, infinite path and UI redundancy. From the talks above, it sounds like they've essentially already transitioned 90% of the PSS, and this is the last hurdle. I'd be willing to bet we've been using all the modern PSS infrastructure for months, and all the functions have been duplicated on both PSS's. AA/US took this route and essentially started it, did it for 345 days and by the end, there was no more new bookings on the old US platform, and everything was in SABRE.
I'm not going on the ship of absolutely zero issues, but these transitions have been happening in the background for years and we've never really seen any issues.
