migrating Sandbox (API version 30.0) to Production (API version 29.0)

We built a customer portal in a sandbox  API version 30.0. We have a staging and a production site API version 29.0.
When we use the ant migration tool we get the following:
BUILD FAILED
C:\Users\grayh\Documents\Forte - Salesforce Customer Portal\Migration tool files\test deploy 03-23-2014\build.xml:75: Failed to login: UNSUPPORTED_API_VERSION - Invalid Api version specified on URL

Is there a way to get around this short of upgrading to version 30.0?

Thanks you,
Haya

Hi Haya, 


Change the package version to 20 in Sandbox and then try to deploy. 

If that does not solve the issue, you may contact Support.
