    What model number are the servos.? Doubt they will be any different to any other servo. Will just be 3 phases on one cable. Encoder on other.
    You'll just need to know what type of encoder ie Incremental or Absolute. If absolute then you may need to change for incremental.
    If incremental but single ended signals ie: common Gnd then you will need to either buy or make a line driver to turn into differential signals.
    Older Single ended encoders tend to be low count so may want to change for differential encoders with higher count and save the hassle of line driver and increase resolution.

    If Inc and Diff encoders then it's just case of knowing the pin outs and line count and your sorted.!
