Generating data migration plan for in-place encryption of data

Methods, systems, and computer program products for generating a data migration plan for in-place encryption of data are provided herein. A computer-implemented method includes receiving, from a user, a request to generate a migration plan for performing in-place encryption of data within a database, wherein the migration plan indicates periods of time in which portions of the data are to be encrypted; determining a set of constraints for performing the in-place encryption; generating the migration plan based at least in part on the set of constraints; and performing the in-place encryption of the data in accordance with the migration plan such that only a single copy of each of the portions is maintained during the in-place encryption, wherein the single copy comprises one of a plaintext copy of data corresponding to the portion, and an encrypted copy of data corresponding to the portion.
