The DWP has confirmed in its LA Welfare Direct 6/2022 guidance-
'17. From May 2022, we have started to write to claimants on legacy benefts to let them know that they will move across to UC and explain how the process will work. The letters to claimants are called ‘Migration Notices’ and will let claimants know that their legacy benefts are ending and that they have three months to make their UC claim. To make sure our claimants are fully supported, initial volumes of claimants moving through the process will be small and controlled; initially fve hundred across two locations, Medway and Bolton.' and 19. A dedicated helpline, signposted on the notice claimants receive, will provide support for people to make their UC claim and guidance will also be available online including on the Understanding Universal Credit website. Those in need of further support can also visit their local jobcentre.
