A vendor requires specific editor versions for different report templates: JasperSoft Studio 6.6.0 and 6.21.3, and iReport 4.5.0 and 5.0.0. Updating them is not currently an option.
The proposed server upgrade is to Windows Server 2025, with 2022 or 2019 as alternatives. Where can I check compatibility, and how would you approach testing it?
I'd start with the application vendor, since they require the exact editor versions. Ask which Windows Server versions they support for each one, and whether they have a tested configuration including the required Java version.
Check the product documentation for those specific releases too. A version running successfully is not quite the same as the vendor agreeing to support it, so it helps to get both answers.
The practical answer is a test VM. Try the four editors on Server 2025 first, then work backward to 2022 or 2019 if something fails. Your MSP may be able to help set that up, even if they don't support the applications themselves.
Don't stop at whether each program opens. Load a representative template for each application, edit and save a copy, and check that the resulting report works in the vendor's system. Record the Java configuration and any errors so you have something useful to take back to the vendor. Check the cost and licensing of a test VM before setting one up.
Keep the four versions separate in your compatibility notes. A successful test of one JasperSoft Studio version doesn't establish that the other Studio or iReport versions will work, especially if they need different runtime configurations.
