Hey , I think earthgirl's just about square on the head. If its soaked and youd have to let it sit in water for a few more days , Id take it out , wash all the soil off the roots , and keep it out of a pot for up to a week and let it get nice and dry in the semi- shade. Then , repot it DRY!! dont water at all until it starts to push out new growth , even if the leaves get wilty and start to drop a little. Portulacarias are one of the succulants that produce roots in absence of water , instead of in presents of water . But , once it does start to make roots (ussually shown by new top green growth) you can start to lightly water and gradually move it out into more sun. in a month or two , you can start treating it like any or other trees , as long as the nights are above 60. Once that happens, cut back on your day to day watering so as to help prevent root rot . ANd protect below 45 from the cold , again to prevent root rot.
ALthough EGO already pointed you in the right direction , just thought this may help a bit . BTW , Portulacarias are one of my favorite trees. Jason
