One thing I would add to Daisy's good advice... I would move these plants when the soil is dry, or almost dry, and wait to water until a few days or a week after transplanting. That way if you carry over some soil it won't be wet, and you'll avoid rot problems if the root gets a chance to heal before you water.
The mother of millions is virtually unkillable (I've tried) but you need to be careful where you put it, as the plant will sprinkle offspring all around it (true to the name) and they grow like weeds. Neither plant is particularly needy about drainage but I would recommend a mix with a good amount of (say 25%) perlite or pumice to be on the safe side. Avoid sand as it tends to hold onto water.
