Wedge the plastic opening tool under the charging port board at the bottom of the phone.

Push down on the plastic opening tool so the board pulls away from the phone.

Continue to do this around the charging port board until it comes all the way off the phone.

The board is glued to the case so make sure to work around all edges to ease removal. Trying to pull it away from one edge can cause damage to the board.

After removing the charging port, the adhesive will not have as strong of a hold on the new charging port. This should not be an issue. However, if the adhesive strength is negligible, you can consider buying adhesive and applying it before inserting the new charging port.
