The Bethesda Steam migration will be available in late April 2022, signaling the final days of the Bethesda.net game launcher.
Earlier this year, Bethesda Softworks announced that it was shutting down the Bethesda.net launcher. Games, game data, and currency (such as Atoms in Fallout 76 or Crowns in The Elder Scrolls Online) could be moved over to Steam once the process begins.
Unfortunately, it looks like the plans for beginning this migration were slightly delayed. It was originally supposed to take place in early April 2022; one might note how we're almost at the middle of the month and it has not yet started. Whatever the original problem might have been, it looks like Bethesda Softworks has finally locked in a start date (and an end date) for the move from the Bethesda.net Launcher to Steam.
When Does the Bethesda Steam Migration Start?
The Bethesda Steam migration starts on April 27, 2022, as highlighted by @Wario64. A specific time has not yet been announced. Bethesda Softworks advises gamers with Bethesda.net Launcher accounts to begin the process as soon as it's available. You'll no longer be able to play games on the Bethesda.net launcher starting on May 11, 2022. (A Bethesda.net account, however, will still be required to access the company's games.)
It's not quite clear exactly how the process will work in its entirety. Presumably, players will simply have to click a button to begin the migration process. However, not everything will be automatic -- a caveat in the F.A.Q. section of the announcement notes that some games will require you to manually move over your save files.
Sadly, you're also going to have to redownload your games on Steam. That could be quite a hefty amount of data -- especially for people in countries with metered Internet connections or slow connection speeds. Take care to budget your bandwidth for the move.
