Moving to an Apple Silicon Mac - Any Gotchas?

I'm about to retire my Intel iMac and move to an Apple Silicon iMac, I have my media files and archives on a SoftRAID RAID 1 volume, running SoftRAID 6.2.1.

I was just going to shutdown my old iMac, plug the RAID drives into the new M1 iMac and re-install the SoftRAID driver & software to get the RAID mounted, is there anything else I should do or anything I need to be aware of before I start on this?

First thing you must do is this:

https://support.apple.com/en-lk/guide/mac-help/mchl768f7291/mac
Select reduced security and enable this:
Select the “Allow user management of kernel extensions from identified developers” checkbox to allow installation of software that uses legacy kernel extensions.

then you can install the SoftRAID driver and "Allow" OWC as an identified developer.

Note: if this is a RAID 5 volume, a % of users, I would guess 2-5%, get kernel panics when their enclosure is connected. There are some workarounds available.

Other than that, it should be easy to migrate.

@softraid-support awesome, thanks!

Are there plans to move away from kernel extensions in the future? Also, resizing APFS volumes 😏

@dgiffin 

Apple has announced they are moving away from kernel extensions in the core, moving them to "user space", but have not released the developer kits for this.

APFS resizing is going to require more APFS documentation. We do not have the tools to do this yet.

@softraid-support I can wait, they’ll come in time I’m sure.

I followed your suggestions and the migration to my new Apple Silicon iMac went like a charm - thanks very much.
