I agree with Stefan,
If manual archive log shipping/copy is your option, then just do a full backup restore and then transfer all the archive logs on DC2. During cut-over you can stop the DC1 instance and apply all pending archive logs on DC2 then do post recovery steps, it's simpler for small databases.
DG is not at all required for this.
If your database/environment is large in size, then the smooth cutover can be done using DG (Mentioned by RB in his update). It need very minimum downtime of primary and you need to do (almost) nothing other than post recovery during cutover.
