Can old flex sample viewer application work when upgrade to arcgis10 REST service?

[cristiBJ]

My old application was developed based on sample viewer and arcgis flex api 1.3. Now the gis department need to upgrade system to version 10. They will regenerate the REST map services. Will the application still work? Thanks a lot.

Yes, the ArcGIS REST API is backwards compatible.

Thank you. I thought this was forward compatible. I will test it too.

Yes, most of my flex apps are 1.3 and they work well.
