If you look in your zone_points table for innothule, you will see that zone point number 1 leads to sro (target_zone_id 35).
To make this zone you to the new southro, you would need to update it with the target_zone_id for southro (393) and the correct x,y,z coordinates for the new southro zone.
Like this:
Code:
UPDATE zone_points set target_y = -596, target_x = -342, target_z = 146, target_heading = 199, target_zone_id = 393 where zone = 'innothule' and number = 1;
I got the target coordinates from a packet collect, but you could just as easily find them manually by #zone southro and finding roughly where the player should appear after zoning in from innothule.
Of course innothule has been revamped as well (as innothuleb).
