# Migrating between Share and Enterprise

### When migration is required

You may need to migrate between Share and Enterprise when:

* Moving from trial to production
* Changing hosting models
* Adopting new security or compliance requirements
* Migrating Tableau Server to Tableau Cloud (or vice versa)

***

### What changes during migration

* Extension hosting URL
* Extension configuration references
* Deployment responsibility

***

### What stays the same

* Core product functionality
* Workbook logic
* User experience

***

### Important note on extension URLs

Tableau stores the extension URL inside the workbook.\
When environments change, the extension URL must be updated.

See **Tableau Platform Support → Environment changes & URL migration** for details.

***

### Summary

* Share and Enterprise offer the same features
* The choice depends on hosting, control, and compliance needs
* Migration is supported and does not require rebuilding workbooks
