Pos alignment before root motion

Hi! I have next problem:
Player performs climb movement via root motion (because of out of the box netsync), but before player should be aligned properly to start position/rotation.
How to implement those aligining? I saw examples with lerping between current and target pos/rot, but in this case we disregard animation.
Also pos aligning should be integrated to existed client side prediction, what shoud be done with great care (looks like simpler version of root motion syncing).
