# Upgrade to a Multi-Org Account

With Marketing Cloud Connect for Marketing Cloud Engagement, multi-org accounts offer flexibility, but upgrading impacts the underlying structure of your Enterprise 2.0 account. Before upgrading, review these considerations for compatibility. The upgrade requires a minimum of 2 hours.

Before you begin, ensure that your account meets these requirements.

- Enterprise 2.0 Engagement account with multi-org is enabled.
- Marketing Cloud Connect managed package version 5.494 or later is installed.
- Your Engagement admin configures your custom profile.
- Multiple Sales or Service Cloud orgs exist.
- Licenses are available for Engagement API users and Salesforce system users.
- Multi-org doesn’t support custom fields in webcollect. If the form contains custom fields, we can’t collect the data supplied by the subscribers.

![Important](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_cross-cloud_products-264-0-0-production-enus/bd617332-480f-48e8-b283-3477883c1320/images/icon_important.png)

Important You can’t turn off multi-org after it’s turned on.

1. Log a support ticket in Salesforce Help for the upgrade.
2. Pause all Engagement email sends through the Sales or Service Cloud until the upgrade completes.
3. If you use Synchronized Data Sources, pause data synchronization across clouds until the upgrade completes.

    Important When using multi-org with Synchronized Data Sources, ensure that the tracking user is connected to less than five business units.
4. To improve performance, after you upgrade to multi-org in an existing account, reconnect previously connected business units.
