[SalesForce] How to migrate default home flexi page assignment from one organization to another using ANT Migration Tool

Finally got the right way!, same certificates can be installed across sandboxes with the the below steps: On the source sandbox

1. Security Controls -> Certificate and Key Management
2. Click on Export to Keystore
3. Provide a Keystore password
4. Click on export
5. A file Java Keystore format with extension .jks (e.g. 00D180000001XWw.jks)

will get downloaded to local system

On target sandbox

1. Security Controls -> Certificate and Key Management
2. Click on Import from a Keystore
3. Choose downloaded jsk file and provide Keystore password and click on Save
4. All certificates inside the Keystore imported to target sandbox.

click the checkbox of folder sharing 'Enable access level of sharing reports and dashboards folders'

What i have previously observed is that usually if source org has folder sharing enabled and destination does not have ,we get this unexpected error .Certainly something sfdc needs to take care

Quick fix for the same is to check the folder sharing in destination if source has this and then try deploying the same .

Hope this helps you.
