Faction changers (help me please)

Unable to enter the Dragon Isles after faction changing (From Horde to Ally). The boat is unavailable and the portal is unusable. Has anyone else faction changed from Horde to Ally (at lvl 70) with a solution?

Also, the initial starting quest at stormwind keep isn’t available (figured it wouldn’t be since lvl 70…)

Looks as if boat is available. Just saw it leave the harbor from Mage district.

Can see the boat from Mage district; upon approaching the docks phase and the ship disappears.

Only solution is to complete the entrance scenarios to the other expansions or something?

SOLUTION: Accept the “To be prepared” quest in Stormwind Harbor (Run scenario or skip via “Heard this tale before”.)

Phased to current Stormwind Harbor and the boat to the Dragon Isles is now available.
