Can Partnership be converted into Limited Partnership (LP)?

Yes. A Partnership can also be converted into an LP where one or more (but not all) of its partners register themselves as limited partners. The resulting LP formed must also register itself as an LP under the Limited Partnership Act. Where a person deals with a firm after it becomes an LP, that person is entitled to treat the firm as a general partnership until he has notice of the registration of that firm as an LP. He is also entitled to treat any person who was a partner of the firm as a general partner of the LP until he has notice of the registration of that person as a limited partner.
