2004880 - Migration Error: "ISO codes for start date and time not valid"

When performing the migration of customer contracts, the following error message occurs:

ISO codes for start date and time not valid

1. Go to the Business Configuration work center.
2. Select the Overview view.
3. Search and open the activity Migration Of Customer Contracts.
4. Click Migrate customer contracts using the migration tool.
5. Select the XML file which you maintained previously.
6. Click Execute Import and select the Step-by-Step option - the following error occurs during the Simulate Import step:

ISO codes for start date and time not valid

When checking the  file in the migration tool, the dates are not following the correct format. The valid ISO code date format is : YYYY-MM-DDT00:00:00Z. Still, when uploading the correct dates in the migration tool, the dates revert to the previous incorrect format. 

The date entered for the Contract End Date is wrong. For Example, the Contract End Date entered for one or more contracts has been maintained as YYYY-MM-DT00:00:00Z instead of YYYY-MM-DDT00:00:00Z. If the value for DD (Day) or MM (Month) contains only one digit (e.g. day or month value from the number range 1 - 9), please input the digit "0" in front of the DD or MM value. For example, if the Contract End Date is the 1st of March YYYY, the correct input will be YYYY-03-01DT00:00:00Z, and not YYYY-3-1DT00:00:00Z.
