Hi We need to upgrade our Nexus Repository Manager since a critical security vulnerability was found in 3.26.1 and the earlier version. At the moment our Nexus Repository Manager is OSS 3.16.1-02 Anybody can share their experience with their upgrades and what to be aware of. Any risk for losing existing data or something no longer will work. I will surely make a backup before I start with the upgrade. Is it possible to upgrade directly to the latest version and if It is not possible, then which version shall we go for. If anybody can share a Guide to upgrade it will be fantastic. Thanks. ---

As I can see the latest version is 3.37.2. Going from OSS 3.16.1-02 to 3.37.2 is a big jump. Is the upgrade straightforward, or is there any pitfalls, challenges I have to be aware of?. ---

Thanks, did succeed to upgraded to nexus-3.37.2-02. Meanwhile, nexus- 3.37.3 was Released so I tried to upgrade to this version. But this was not possible, I faced the following problem when I executed nexus.exe /install. _Scan type: Auto-Protect Scan_ _Event: Security Risk Found!_ _Security risk detected: Unproven.LowPrevalence_ _File: d:\nexus-3.37.3-02\nexus-3.37.3-02\bin\nexus.exe_ _Location: Quarantine_ ---

Great to hear you succeeded. The issue that prevents you from another upgrade doesn’t come from our product. It sounds like some kind of a scanning software that prevented you from running newer version, perhaps a virus scanner? If so, you should be able to release the binary from its quarantine and continue your upgrade. ---

Hi Already did that, something is wrong with the file nexus.exe in nexus-3.37.3-02. No problem with nexus-3.37.2-02. ---

I’ve just scanned the binary with [VirusTotal and it the report seems fine](https://www.virustotal.com/gui/file/bb01b400032359f56ef5c3a04c533390525b178d88f95716d0c2acad5bd38a9a) to me (there’s one false-positive there). I’m afraid I won’t be able to help anymore here, please contact your administrator or your virus scanner vendor and report a false-positive to them.
