Can I sync master data between two completely different Business Central tenants?

No. The native Master Data Management feature only works within a single environment. Companies in separate tenants require a different integration approach, typically involving APIs or a third-party integration tool.

Does enabling synchronization sync historical transactions too?

No. This feature is built for master data, meaning non-transactional records like customers, vendors, and items. It does not synchronize posted transactions, invoices, or ledger entries.

What happens if I couple the wrong records by mistake?

You can remove an incorrect coupling from the coupling screen. It is far easier to catch this early, so always review coupling matches before running your first full synchronization rather than after.

Is bi-directional synchronization ever a good idea?

Microsoft advises against it because of the conflict risk, and in practice we agree. If you find yourself needing true two-way sync, that is usually a sign you need a more sophisticated integration approach than the native feature offers, not a reason to force bi-directional sync anyway.

How long does the initial full synchronization take?

It depends entirely on how many tables, fields, and existing records you are syncing. A small dataset can complete in minutes. A large item master waith thousands of records and multiple linked tables can take considerably longer, so plan the initial sync outside of business-critical hours.
