I also would not replace it until you need to.
I put a Rheem from HD in about 7 years ago with a 7 yr warranty. How convenient for it to start peeing all over my basement floor at 7 years 4 months.
If you do end up needing to, at least they make copper fittings called Sharkbites that work awesome for this type of job in particular as you might not need to solder at all depending on your current plumbing.
