  1. Add a new migration: Run the following command in the Package Manager Console to create a new migration:
Add-Migration UpdateFieldData

Replace UpdateFieldData with a meaningful name for your migration.

  1. Write the migration code: In the Up method of the migration, write the code to update the field data. For example, if you want to set the value of the Field1 column to the value of the Field2 column for all rows in the table, you can use the following code:
migrationBuilder.Sql("UPDATE TableName SET Field1 = Field2");

Replace TableName with the name of your table, Field1 with the name of the field you want to update, and Field2 with the name of the field you want to use as the new value.

  1. Apply the migration: Run the following command in the Package Manager Console to apply the migration:
Update-Database

This will update the field data in your database table.

Note: Before running any migration, make sure you have taken a backup of your database in case anything goes wrong during the migration process.
