We actually do have an option for upgrade from Yoga directly to Antelope (2023.1).

Yoga was the first "experimental" slurp release, where teams were practicing on how to organize the process and tools.
While it's not an official slurp release, upgrade from Yoga to 2023.1 went really smoothly for us.

But skipping upgrades from Train to Yoga is way more tricky.
I personally had a following upgrade path in one of orgs:
T->V->X->AA

But these were not super smooth and had a couple of quirks down the road, as well as some manual db updates.
Though not *so* terrible and imo - was worth the saved time...

Hi Danish,

OpenStack 2023.1 Antelope is the first SLURP [1] (Skip Level Upgrade Release Process [2]) release. If your target version is Yoga - you must complete upgrade procedure in N+1 cycle.

Dear Team,

We have few openstack-ansible Train release in our environment. We want to upgrade these setup to atleast Yoga release.

Currently we are doing upgrade step by step. like from Train to Ussuri then to Victoria then to wallaby and so on(in N+1 series).

Can we skip few releases and directly go to Yoga or any other feasible release?

Regards,
Danish Khan
