upgrade from 11.2.1 to 11.5.1 failed

Hello friend,

I must thank you for not leaving me alone :)

I carefully performed the upgrade again in a Standalone BIGIP 4000s box. I applied your suggestions and everything worked, except that the configuration could not be loaded, so I issued the "tmsh load sys config" command and it displayed one error about some pool which did not find a corrsponding node. I modified the bigip.conf by using the vi tool. Finally the configuration was loaded and the standalone BIGIP had the 11.5.1 version.

Sincerely, I am afraid of getting an issue related to a fail in the loading of the configuration when I upgrade the HA system. I think the configuration loading must be smooth.

Moreover, I realized that the virtual servers are not attached to a link after the upgrade. I must tell that I do not have an active link in such data center. Maybe, do you have any comment about? Please, find below the images related:

Thanks a lot. Really, you helped me.
