A handful of users have recently gone through this process. A direct upgrade from Big Sur to Ventura is possible, but very likely it will fail.Hello! I've been using this system for 2.5 years and never experienced a single problem. I am still on Big Sur 11.2.3 and have not made any changes since that update. I think my opencore version is still the one from October 2020 when I first installed the system. But I'm finally thinking of upgrading to Ventura. Can I do that directly from 11.2.3?
Also, I currently have a 512GB SDD. I want to upgrade it to a 1TB. Can I use Disk Utility Restore function to create a clone and be able to immediately use the clone on the 1TB to boot?
Thanks in advance for the advice!
Recommendations:
- Make a full bootable backup of Big Sur
- See STEP 11 of this post
- If you skip this step you might lose all your files and applications
- Test the backup disk to make sure it works then set it aside
- It must be an external disk
- An NVMe or SATA SSD in a USB 3.0 enclosure works well
- NOTE: Samsung NVMe SSDs are no longer recommended because trim does not work and boot times can increase substantially
- Which version of OpenCore are you using?
- Simply run Hackintool and select Boot tab
- Simply run Hackintool and select Boot tab
- If it's older than 0.6.6 then it will be necessary to install the OpenCore 0.8.3 EFI folder from Post 1 and copy serial numbers from current config.plist -> PlatformInfo -> DataHub into the new config.plist.
- After installing OpenCore 0.8.3, boot the system to make sure it works
- Download and run latest version of HackinDROM app
- Then follow the link at the top of Post 1 called Update to latest OpenCore by following this guide for instructions on using HackinDROM
- After OpenCore 0.9.1 has been installed, reboot and make sure system works
- Now attempt an in-place upgrade from Big Sur to Ventura
- If the process fails, it will be necessary to make a fresh installation of Ventura and:
- Either use Migration Assistant to transfer files and apps to Ventura
- Manually copy files and reinstall applications
