Backward compatibility issue

[obszczymucha]

 Hi!

 

I am using JasperReports 3.1.4 and I'm considering upgrading it to at least 3.5.x version or the newest if possible.

However, I'm concerned if there will be any backward compatibility issue with my .jasper files created for JasperReports 3.1.4?

 

Thanks!

It may not be applicable to those specific versions, but the team I am on at work uses JasperReports 3.5.2. On some projects, we use that to run reports compiled with 2.0.5.

 

My experience is that JasperReports is very good with backwards compatibility.

 

Ideally this would be a moot point, but sometimes you just can't upgrade jar files willy nilly. The risk of breaking production code is too great. However, the only real issues I had was upgrading past the 3.5 barrier which introduced some redesigns and refactorings, and adjusting our custom build process to work with it. But the reports ran fine, and now everything just works.

The closes the version are together the more likely the formats will be compatible. We went from 1.3.3 to 3.7.4. WE had to recompile all the reports because even the most basis report would not run without errors.
