Hi! Im getting this error when I’m trying to upgrade my 8.0.15 installation to 8.1. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/e/be430462fc65d8187a2afb641fe358def5f1cee6.png) Is this normal? ---

I upgraded a development server from 7.9 to 8.1 and this happened as well. I just ignored it and continued. Everything seemed to be fine when it completed except I had to upgrade one of my modules to work with 8.1 manually. ---

Ditto, same here. They have not updated their modules for 8.1 yet. From Sepasoft support on 11/16... > unfortunately, as you can see on our Download Page [Sepasoft MES Modules Downloads & Resources | Sepasoft](https://www.sepasoft.com/downloads/#Platform_3_Ignition_8) our Modules for Ignition 8.1 (it will be released for us in 3.81.0 XX so most likely a new Tab) are not yet available and still being tested by our QA group. > > please check back regularly. I cannot reasonably give you an ETA and I apologize for this ---

From the log it looks like one of the files is locked and couldn’t be updated: ```auto java.nio.file.FileSystemException: C:\Program Files\Inductive Automation\Ignition\data\jar-cache\com.inductiveautomation.alarm-notification\ __1656306470__ alarm-notification-common-5.0.15.jar -> C:\Users\IGNITI~1.ADM\AppData\Local\Temp\_ignition_preinstall_temp462799030176962224\data\jar-cache\com.inductiveautomation.alarm-notification\ __1656306470__ alarm-notification-common-5.0.15.jar: The process cannot access the file because it is being used by another process. ``` You could check what process has it locked using process Explorer in Windows? > **[Process Explorer - Windows Sysinternals](https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer)** > > Find out what files, registry keys and other objects processes have open, which DLLs they have loaded, and more. Otherwise, reboot and try again perhaps? ---

UPDATE: I’ve halted the test until another process is done (Database rellocation). After that’s done, I’ll resume the testing.
