I wonder if there are any community-approved guidelines for updating a moderately old system (i.e., Elixir 1.9.0 compiled with Erlang/OTP 20) with a whole bunch of older libraries.
My intuitive approach would be to
- first apply all the non-breaking updates for all the libraries that will still work with my Elixir/OTP, then
- update Elixir and OTP to the current ones, and then
- again update all the libraries,
probably repeating this several times and rewriting some outdated code.
Is there any better way? What tools should I look for? Is there probably some book on the topic?
Thank you all in advance!
