How can I run a Rails 1.2.5 application on ruby ​​1.9?

Question

I have an old application made on rails 1.2.5, this application has great access per day.

I intend to upgrade my server (joy accelerator) to run ruby ​​1.9.x and work with rails 3, but I can not stop or move this application to another server.

Is there any way to run this application on ruby ​​1.9? or run simultaneously two ruby ​​versions (1.8.7 and 1.9)? or in the latter case, upgrade my rail application 3?

Thank.
