12 Speed Shimano Ultegra DI2 Upgrade / Part 2 of 3 | fixing shifting issue

Being fortunate enough to get my hands on a 2021 Giant TCR frame & fork last year I upgraded my bike. Knowing Shimano was on the cusp of revealing the updated group-set I used my older cable actuated DI2 miss-match group anticipating upgrading in the future. Fast forward a little over a year later, I took a couple months to compile all parts to upgrade to the new Shimano Ultegra DI2 12 speed. Here is a list of parts and tools I used.
