I asked about this before, but I am here again because it just got more complicated. I need to do four things:
Switch hardware from a Pi 3B to a Pi 3B+
Upgrade from Jessie to Stretch
Upgrade from the Romeo Golf fork with MySQL database to the main 2.6.1
Preserve database entries and performance data
The data is stored on a Western Digital PiDrive. So those are my goals. My question is what I need to do to accomplish them. What order should I go in? What are the commands to preserve my MySQL database and collectd data? How do I do this without screwing up and losing everything, while incurring the least amount of downtime?
Any advice is appreciated…
P.S. I am an old school Unix guy from before this fancy ‘Python’ and ‘Linux’ so I need a little help with more advanced stuff, but have the basics down pat.
