Skipping the sequence number in a project

[Prateek Phadke]

Is is possible to skip specific number(s) in a project while creating new issues?

In one of the projects, I need to reserve a series of numbers let's say between 100-500 for another set of issues that I will migrate from another project. 

Essentially my new project will have an Issue id key like SPS-1 up to SPS-100. and the next one; when created must take the id as SPS-500.

What could be done here?

No.  You could hack the database to increase the counter, but all import methods then carry on from the highest number, so it won't use your "reserved" numbers.
