Rebanding
Several elements have to be true before a scanner will stop working on a rebanded system. I looked at the DB page for your county, and only see 3 trunked radio systems there. If you are not scanning a trunked system, all you will have to do is program in the new frequencies and you are good to go.
Is the system a Motorola type trunked radio system? If not, and you were able to monitor the system before rebanding, just program in the new frequencies and you're good to go.
If the system is Motorola, and rebanded, do ANY of the voice frequencies fit the format of 8xx.xxx0 MHz? (Note the zero in the 4th position after the decimal point.) If so, your scanner will not track to these frequencies. Otherwise, it will.
