Sure is.
Best to do a bit of preparation though.
File New - and set the project start date in Project/
Project Information.
Select all the old tasks and paste into the new file
The project will start from the Project Start Date you set.
I suggest making sure all tasks are - As Soon as Possible.
If you have a large # of tasks, an easy way to do this is
Insert / Column/ and select Constraint Type, and check,
and reset where necessary.
I would link all the tasks at this stage, being careful
not to include any summary tasks in the linking process.
You mentioned keeping the durations. If so insert a column
fo Type, and select fixed Duration. That make you the
master of Duration.
You haven't mentioned resources, but you can copy them
across no problems. Perhaps consider setting up a Calendar
to use as your base calendar.
Actually, you can do all this by saving your old schedule,
and just changing the Project Start Date in
Project /Project Info.
Hope this is what you were after.

Is it possible to take an old project and use all the old
tasks and just change the project start date, and use all
the durations?? If so how?
