Which is why the EA uses the Hyperion all the way from the mid 22nd century to the demolition of B5 in Sleeping in Light?
Not necessarily. That could very well be a "preserved" cruiser, perhaps the infamous "Hyperion" herself, turning up for the special occasion.
However look at it this way - The EA has a lot of them compartively as they were a mass built hull; By your reckoning they should have been refitted with rotating sections when that technology became available with the Omegas because that would be better. Basically, the Hyperion went from the "Ship of the Line" to a more auxillary role. When true AG equipment became available, it wouldn't be as simple as just plugging it in and turning it on.
The Hyperion was designed as a zero G ship. It's quarters, corridors etc are designed without the considerations of a gravity. She'd not have a prefered "up" or "down" direction to her interior surfaces, so the entire interior space would need redesigned, corridors would need to accomdate the new sense of down and be tall enough (they might not be). Doors would need to be reoriented throughout to the new "down" .
Alternatively, you could use the yard space that this cruiser is taking up during her refit to build a new Frigate (the Chronos) that is as effective in most roles, and then slowly run the Hyperion fleet down as they life expire.

It wouldn't be quite as good as the Minbari system of full integration, but conventional engines and artificial gravity, as someone above mentioned, work fine for the Centauri.
The Centauri use a semi-gravitic drive system though (this goes back to series fluff, I can't remember is this is reflected in the source books (it was in the Babylon Project RPG and B5Wars game). Not a fully fledged system like the Minbari's, and with a greater number of conventional thrusters.
