Should I transplant

I have this hibiscus which I do not know the name of planted in a pot. I have had it in the same pot for about 10 years. It sat on my front porch for years where it didn't get much sun and never really bloomed. This year I put it out by a brick wall where it gets morning sun. It is doing great and has bloomed like crazy this summer. I am wondering if I should try putting it in a new pot with new soil. I am afraid it will die as it seems happy where it is. Does anyone know the name of this hibiscus?

I also have this double hibiscus which I think is beautiful but I don't know the name of it either. I bought it as Lowe's and it didn't have a tag.

bobyrd, 10 years...yep, I would pot it up with some new soil.
It's name is Hibiscus 'Albo Lacinatus'
