As for the character there should be nor problems.
And as pumas mentioned, worst case scenario, you'll have a seasoned character in a new world. However, do remember that as long as you can see the old world on the list, you can also get the seed reference to remake it should you wish to carry on (you would have to explore and build again, but on the other hand you would know roughly where some things are).

Yes, old world worked, But was laking some things Or it was old backup,
