After updating, deleting or adding new profile property in test farm I want to syncronise change to pre-prod and then production. Is there a recommended method to accomplish this with or without third party solution? Mike BMike B

You should do the same steps (udpate, delete or add) the user profile properties to the other farms. In order to replicate the user profile property values, you can use the User Profile Replication Engine from the SharePoint Administration Toolkit. Thanks, DipDip http://dzeee.net/sharepoint

User profile replication tool that comes after installing administration tool kit provides you the option to replicate user profile property values between 2 seperate SSP or Farms. If you add a new profile property in your source SSP, you would need to create the same profile property in the destination SSP as well. UPR will only replicate the profile property values.
