Potty training a child can be stressful, so I would consider that. Do you really want to add more stress during an already stressful time? Moving isn't going to be stressful just for you, it will be stressful for your daughter, as well. Children are resilient, but your daughter will also go through a time of instability and readjustment to her new environment. Even children who are already potty trained often relapse when they move.
My advice would be to wait. It is true that it is better to potty train children when they are ready. A two-year old is generally not ready, but of course, there are exceptions.
If you haven't done so already, you might try purchasing a toddler "potty" chair. This way your daughter can get used to it before you move. If she "takes" to it, you might try seeing how she does before you move, but don't force her. Children typically will urinate in a toilet before they will defacate in one.
Ordinarily, I would suggest using something like huggies pull-ups, but I'm not sure that your daughter is old enough to use them. I can say that when toilet training, though, it helps if the child is not still wearing diapers, cloth or otherwise. Either huggies pull-ups or training pants would be better. Diapers confuse the child and they're not able to take them off to use the potty.
Again, my advice would be to wait. You daughter is going to go through two stressful events - moving and the addition of a baby, which means she will get less attention from you and will have to adjust to both a new location and a new sibling and therefore, a new place in the family order. The less stress she has, the better her adjustment to both events. Since potty training can be stressful for parent and child, I do think it's better to wait until things have calmed down somewhat and she is developmentally ready to potty train.
