I have run an RPi Issue 2 as a Data Server for just over 10 years, and consider now that I should upgrade the system to an RPi 4, at the same time updaring the three 4TB hard discs to SSDs.
The OS is Debian V7, Raspian Wheezy, probably installed in 2014 or so, but frequently updated and upgraded.
I am desperately trying to avoid installing an OS from scratch, as I would then have to rebuild all theadditional component software.
So, may I ask: Is it possible to run an OS installed on an SD card on an earlier RPi variant, on a later variant? That is, installed on an RPi v2 on an RPi 4. I have tried this but unfortunately the previously installed version does not seem to wish to boot on the newer RPi variant.
As mentioned above, I am hoping that I won't be forced to install and configure the complete server setup on the Issue 4 RPi.
Any advice will be much appreciated. Thanks in advance.
