USA Changing Chart of Accounts

Can I change the COA in QBO, or would it corrupt the data?

I did a company's nonprofit books through 2015, then another treasurer took over and changed the COA and used QBO. I am now trying to fix the problems created and need to amend 2016 and file 2017 taxes, so putting the COA back to how it was for 2015 would make it easier since keeping the last two years of records as-is is not needed. We plan to convert back to QB desktop for 2018.

Thanks in advance.
