@NiteshLal The best way I can think of is first migrate CM from packages to Parcels due to the matter of fact that it’s always easy to manage a cluster using parcels.

Now, once you migrated to parcels using above doc you will have a CDH 5.16.2 with Cloudera Manager parcels. Then you can upgrade the cluster as well CM to 6.3.x using simple upgrade doc.
