Manage multi currency and credit notes while migrating to cloud

SUGGESTED

We want to upgrade from Sage 50 desktop to Sage business accounting Cloud. However, When we are trying to create the JSON file with the help of migration tool, It is giving errors for Multi-currency as well as credit notes. Now does that mean Sage Business Accounting didnt supports multi -currency and credit notes ?

How can we manage this situation ?

How to migrate all the data ? Do we need to do some manual data entries ?
