Hi,
I'm afraid we have no further information regarding ESA reassessments. You might recall that there was never a public announcement about the delay, the information was gained through an FOI request. I wouldn't expect there to be an announcement when they recommence either.
As to claimants with indefinite DLA, the DWP have recently said that they intend to bring forward the migration and start straight away, as seen in this news item :
