Prior to v2.0, YSQL was still in beta. Upon the release of v2.0, a backward-incompatible file format change was made for YSQL. For existing clusters running pre-2.0 release with YSQL enabled, you cannot upgrade to v2.0 or later. Instead, export your data from existing clusters and then import the data into a new cluster (v2.0 or later).
