Which actions should you take to prepare the file for conversion? Select all that apply.

Preparing a QuickBooks file for conversion to another system or version involves ensuring that the most relevant and necessary information is retained while eliminating anything that could cause confusion or redundancy post-conversion.

When considering the action of deleting customized reports that the client no longer wants or needs, it is essential because this streamlines the report list and focuses on the reports that are truly valuable to the client's current operations. This step helps in creating a cleaner and more relevant file for the conversion process, which ultimately leads to a more efficient transition and minimizes clutter.

In contrast, other options concerning deleting all reports, unfavoriting reports, or deleting non-customized reports may not align with best practices. For instance, the practice of deleting all memorized reports, regardless of their relevance, could result in losing important reports that the client might still need. Similarly, unfavoriting reports could lead to unnecessary loss of visibility for reports that may serve a purpose, whereas deleting non-customized reports might eliminate options that could be customized later on by the client. Hence, focusing specifically on removing customized reports that are confirmed as unnecessary ensures that only the most pertinent information persists through the conversion process.
