@rajvi-elastic , can you please re-visit the table summary at the beginning of the PR.
The counts before and after migration are not matching. Also, the linked issue is tagged as having a workaround.

@agithomas, I have updated the summary table and added one more column for the new control panel to avoid confusion.
