We just went through the same over the course of the last 2 years.
Replaced our 4G/8G's with 440's or 880's (depending on box load).  440's
work great, we have them in both PE's and ASBR's.   We run pretty much the
full gamut of services.   We even accidentally upgraded a PE with 440's to
6.5.3 with appropriate SMU's.  We don't plan on backing it down unless we
run into a support issue with TAC.  IPV4 labeled on 6.4.2 to a 5.3.3 is an
issue - doesn't work quite right.  With everything 6.4.2 or higher, it's
