I checked it was a little on the dry side. Gave it a bit of some water and seems to perk up a bit.

Give it plenty of water, not 'a bit'. And then leave it for a good while, ie at least a week, before watering again.

Ok, will do and thank you!

Our sage has overwintered the last two years and now this spring it has bolted. Is it now time to pull it up? I don't know much about most herbs. Any help or suggestions would be very much appreciated.

Sage doesn't actually 'bolt'. That term is used for annual or biennial vegetables which have run to flower, presaging their demise. Sage is a hardy sub shrub which flowers as a matter of course. It's normal. If you don't want the flowers clip them off. Clip them anyway when they fade. To keep sage neat harvest or clip regularly. Your sage can live for years. You only need to pull it if it has become something you don't like the look of.

There are no catchall rules for herbs. The term is a convenience relating to their use, not a botanical category. Each is an individual species and needs care appropriate to itself.

It will sometimes wilt a little after transplanting. It will be OK once the roots are established. About 10 days.
