Error upgrade to SFOS 19.5.3 on a XG550

Good day Sophos Firewall community,

Please help, we have a XG550 appliance and we are not able to upgrade firmware to SFOS 19.5.3. We are receiving the following error when upgrading:

New firmware could not be uploaded. Please refer to online help for possible reasons

Also, have this message on the control center:

You can't upgrade to 19.5 MR1 and later versions. Routes configured through the Zebra advanced shell CLI commands in earlier versions become unavailable in these versions. See KB-000044696.

Followed but could find a solution

Please help.
