Find-and-replace to add a number to all numbers above value X

[DKMusic]

In the example below, I need to add one to all numbers above 297. So 296 stays 296, but 308 becomes 309, etc.

Is there any easy way to do this?

If that's a real Index, and you've added an extra page after 297 (which bumps all the following page numbers), can't you just regenerate the Index.

If you didn't add an extra page, I'm a bit confused why the numbers are off. But as long as it is a real Index, you could add an extra blank page after 297, then regenerate the Index.
