Reclassifying a property

We have a property that we want to reclassify from a surplus asset to investment property. The property has a balance in the revaluation reserve. I have read that the revaluation reserve figure needs to be preserved and the balance in the revaluation reserve for the asset should only be transferred to CAA when the property is sold or moved to assets held for sale. I'm interested to know how others would account for this and the accounting entries they would use.
