Answer: First of all, there is many errors going on here, one advise I can give you is simple. 

1. Use the "IgnoreOnFailure" drop-down menu when importing or exporting data using SQL Server Import Wizard. Keep in mind that you will need to verify the Count(1) or the count of records from and to the Database/Table you are importing or exporting. Otherwise, if you use the "IgnoreOnFailure" you won't see any errors and this might cause False Postive, thinking all the data has been imported or exported when not.

2. Import or Export the data from the tables one by one, or one at a time. I know this is tidious but it can help you not have many errors which will eventually consume alot of time than needed.
