To move devices between join states, i.e. hybrid to entra joined, aka cloud native, the user will barely notice, have a look at PowerSyncPro Migration Agent (https://powersyncpro.com/powersyncpro-migration-agent/), it can reconfigure 10's of thousands of machines in minutes, repermissioning user profile, apps, security, workloads, can also handle bitlocker, AIP and much more.
We recently (in the last 4months) used it to migrate two different companies, 2x 12k+ workstations in a single weekend per company. Worked a dream. 90% of devices were up and running by 10am the Monday morning, the others were international, annual leave or different time zones. Average reconfiguration time was 7 minutes for the user. It will also do offline domain join too.
