I am currently using EE 1.6.9 and plan to migrate to 2.1.
I am currently using php 4.3 and want to move to php 5.
If I switch over to php 5, will it break my current version of 1.6.9? (I still want to run it for a while) Will EE 2.1 work with php 5 without any issues?
I just want to double check before making the jump.
Thank you.
