We have a rails application that’s been running on an old version of Rehat 4.
We have to move it to Redhat 7
apache 2.2.4, ruby 1.8.7, rails 2.3.8, passenger 2.2.5
and we’re expected to migrate to
apache 2.4.27, ruby 2.51, rails 5.2.1 and passenger 5.3.4
This application used gems like
to name a few.
Are there any migration guides that highlight the complexity involved?
