Help with tubeless installation

[Gate closer]

I have Bontranger Duster rims that I am trying to convert to tubeless but am battling here despite following the instructions on the box. I cannot get the rim tape to stick on the existing tape inside the rim that I assume is to stop the spoke holes from chaffing the tube. The question is, am I supposed to remove the existing tape before fitting the rim tape? Please bear with me here as I thought the best thing to do was to try this myself before just dumping at the LBS to convert.

From where I have worked usually the rim tape that comes standard with the rim is removed and replaced with a thicker and more reliable tape which helps with the tubeless installation.

Thanks I thought so but was not sure.

You need to remove the old rim tape.
