ok done it, update went very smoothly. The rescan only needed roughly 30 minutes.
Hopefully that's normal..and all my coins are liquid, i did have a few in reserve to start with but now they are all liquid.
Once again I hope that's all normal...thanks for all the help and holding my hand through this process.

The switch to reserve you saw is a buffer. It takes that when it's close to any block divisible by 200. This is to guarantee that even if the chain reorganizes your transactions will always be valid. So it sets aside some of the liquid if that liquid is close to being reserve.
