 Before you connect a source to Unify, Segment recommends that you first review the default Identity settings and configure custom rules as needed. Segment applies configuration updates to all *new* data flowing through the space after you save your changes. As a result, if this is your first time setting up your Identity Graph, Segment recommends that you get started with a *Dev* space [here](/docs/unify/identity-resolution/space-setup/).

+> Making a space's Identity Resolution rules less restrictive by changing the [limit](/docs/unify/identity-resolution/identity-resolution-settings/#limit) shouldn't cause any issues to existing or future profiles. <br><br> However, making a space's rules more restrictive might have an impact existing profiles that don't adhere to the new rules (for example, decreasing an identifier's limit or changing the [priority](/docs/unify/identity-resolution/identity-resolution-settings/#priority) of identifiers).
+> <br><br>Segment recommends to get started with a Dev space [here](https://segment.com/docs/unify/identity-resolution/space-setup/), test the rules with the expected data, and then create an identical Production space with those rules. Document any changes to a space's Identity Resolution rules, and don't update rules to be more restrictive after profiles already exist outside the bounds of those new rules.
