That is exactly what Ben said. v2.55 knows how to work with the data format from v3, but will not convert it back to the older format. It sounds to me like you would be best served by staying on the LTS version v2.53, which still has bug and security fix support. Why do you want to run anything later? If you *absolutely* need new features introduced in later versions, then you will have to remain between versions v2.55 and v3.x - as there is no rollback to anything earlier than v2.55 without losing data. But that's fine, because if you *need* those new features then you wouldn't be able to rollback anyway. Bear in mind that you will also have to keep upgrading to all v3.x versions to get bugfixes and security fixes, until the next LTS release comes along. If you just want to test the newer versions then do that on a non-production system where you know you'll never need to roll back prior to v2.55 Gavine Xue wrote: > do you foresee any issues if we develop a conversion tool to change the version number in index files back to 2 before a rollback? I think it's fairly obvious that won't work. If the *only* difference between the data formats was the version number, then there would have been no need for a change in the version number. The change in the version number implies that the way that the data is stored has been changed in an incompatible way. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
