7K? Wow.

It's a very tough call when you consider that you have 7K lines of
code that you aren't familiar with it. One note I can share is that
you definitely must examine each contrib module's upgrade
instructions--many *require* that you first upgrade them to the
latest/last 5.x version before moving to 6. And they mean it. ;)

Good luck.
