940 A/C Retrofit - Accumulator Oil/New Compressor Oil 900

I followed the ac retrofit instructions on the FAQs to the letter. They say to add ester oil to the accumulator only if you're not going to replace the compressor. However, if replacing the compressor, you need to add the ester oil to the new compressor, and not the accumulator.

Since I didn't need a compressor (or so I thought) I added the oil to the new accumulator per the instructions. Later, a leak test determined that I needed a new compressor, which arrived last week prefilled with oil.

What should I do now that I've already filled the accumulator? Is there a risk of having too much oil in the system? Also, I suspect the new compressor was filled with PAG oil. Do I need to drain and refill it with ester?

Thanks.
