Content deployment Job Configuration For commerce server Using Sharepoint

Steps to follow

• Deploy the latest build in both authoring and puroduction , make sure that we are not configuring any of the custom features in production
• Delete the site collection for the  Web Application and create an empty site collection for the same by selecting select template later from custom tab
• Do an IIS RESET  in the production farm .
• Make sure that the content deployment configuration of production farm is set to accept the incoming CDJ requests.
• Create the content deployment path and job (Ensure that the user account being used for cdj has admin acess in both the farms ).
• Do a full content deployment Job and verify the CDJ  log .There could be errors related to channel configuraion list , ignore them.
• Delete all channel configuration list and the content type associated with it (from all the subsites/variation site including the recycle bin) and run the full CDJ once again. This is to rectify the errors we get during the initail CDJ run .
• If you have some custom values in Channel configuration list and reenter them if they have got reset during the process
• For each incremental deployment we should be using the incremental CDJ since the full cdj can cause some errors beacuse of the channel configuration list.
