That’s the last moment to copy your progress from PlayStation 3 and Xbox 360.
Grand Theft Auto V was originally released in September of 2013 on PS3 and X360. After a year it was published for PS4 and XO, with graphical improvements and other tweaks. The PC version released in April of 2015. After months and months of support, Rockstar confirmed that additional features won’t be released for old consoled due to technological limits.
All players were allowed to transfer their characters to modern consoles or PC. Now it was confirmed that it will no longer be possible as of March 6th, 2017. If you liked the original release of GTA V and somehow didn’t upgrade, be quick. Rockstar is still expanding the game with feature updates for GTA Online like Import/Export or Further Adventures in Finance and Felony.
