Can I use CWM recovery made for KitKat in Lollipop?

I was already using CWM on kitkat until I officially updated my Micronax Unite 2 A106 (MT6582) to lollipop. But when I tried to use the same recovery made for kitkat in lollipop, it did not work. Why does that happen? Does that mean I can't use recovery made for kitkat in lollipop?

According to xda wiki "The recovery is completely independent of the Android system". Does it mean that, No matter which version of Android I have, the recovery of any version should work. If recovery is independent of android then why does that recovery not working. I am confused.
