HA upgrade to v8

Hi,
according to https://support.astaro.com/support/index.php/Upgrading_to_Version_8 there are 3 ways to upgrade an cluster.
But every proposals brakes the service(=downtime)
To minimize downtime, I'm looking into other options.

However:

A question came up here in the maual. They are talking about:
Disconnect the old master from the network, restart him and break down the HA and the make the update to the v8(please ensure that update is already on the system).

Which file do the exactly mean?

u2d-sys-8.102.tgz.gpg ? or ?
if you press on the tab 'upgrade to v8' Which file will be loaded? If you press cancel, an error message appears: can't save iso image.
Any tipps?

Thanks

The manual described the upgrade process for 7.509 -> 8.000.
With 7.510 the upgrade process is now fully HA/Cluster capable,
you dont have to unplug any nodes.

Start the upgrade process via WebAdmin, Master will start the upgrade process
while Slave is takeing over. Any configuration changes at that point will be lost.
After the old Master successfully upgraded, the Slave will start the upgrade process too.

The downtime should only be a few seconds.
