Failed Upgrade from 4.01 to 4.1

Hi,

Can you briefly describe how the upgrade was done? Did you do the online update or offline update? Have you tried both? What is the appliance disk size?

Hi Joey,

We are using the online method from the UI (similiar to all other upgrades we have done). The appliance disk size is 415GB.

Hi, 

Apologies for delay response. I've been out of office. Are you able to try the offline method, to check if it can help the issue? What is the allocated VM appliance size? Is it more than 1.2TB? 

Hi @DELL-Joey C ,

when we upgraded from 3.10 to 4.0.1 there wasn't a so high requirements on disk size (now we got 2 disks of 415GB each): is 1,2TB mandatory? (600x2?)

The upgrade seams worked for us but we were unable to upgrade plugins after the upgrade so we reverted back to 4.0.1: is the something we have to do before the upgrade?

Thank you

Hi,

the recommended storage space for installing OME 4.0 and all its plugins is 830 GB. However, this is the maximum recommended configuration. For smaller deployments, the minimum storage space required can be lower.For example, for a small deployment with OME and all plugins installed, the minimum storage space required is 600 GB (300 GB x 2 disks). So 1.2 TB of disk space (600 GB x 2 disks) is not mandatory, but recommended for the maximum configuration.Regarding your issue with being unable to upgrade plugins after the OME upgrade from 3.10.x to 4.0.1, the search results suggest taking the following steps before the upgrade:

1. Make sure all installed plugins are enabled on the OME 3.10.x appliance. If using a custom SSL certificate, ensure the certificate chain contains all certificates from the OME certificate to the root CA.
2. Check that debug mode and Field Service Debug mode are disabled on the OME 3.10.x appliance.
3. Ensure there is enough free space on the OME 3.10.x appliance before running the migration.

Following these prerequisites should help ensure a smooth migration and allow you to upgrade the plugins successfully after migrating to OME 4.0 or 4.0.1.
