That sounds like the IR device has moved to a different address due to
the new serial device being on a lower hardware address than your IR
receiver.  Try using udev to make a fixed device name out of the IR
receiver you are trying to use.  This is what I use in
/etc/udev/rules.d/10-local.rules to make sure my mother's Hauppauge
TD-500 remote is always on /dev/lirc0:

# Hauppauge Nova TD-500 remote control IR receiver
SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="2040",
ATTRS{idProduct}=="8400", SYMLINK+="lirc0"

In my case, the idVendor and idProduct values from lsusb are all that
is needed to identify the IR receiver device:

Bus 003 Device 002: ID 2040:8400 Hauppauge WinTV Nova-T-500

Then change your /etc/lirc/hardware.conf:

REMOTE_DEVICE="/dev/lirc0"
