Export printable config?

I've been asked to dump an export of a UTM by a client, and I'm running into an issue doing so. I'm trying to follow this (very old) post on how to export the printable config from a UTM and have hit a snag:

community.sophos.com/.../howto-export-complete-printable-configuration

1) When I try to browse to /var/chroot-httpd/var/webadmin in WinSCP, I get a 'permission denied' error

2) When looking in /var/chroot-httpd/var/webadmin as Root (via SSH), I don't see the folder the link refers to:

/var/sec/chroot-httpd/var/webadmin/var # ls
data_protection_ccl.json  migration_status.json  rrd-nodataimages
feed.ph                   rrd-images             u2d_progress

Is this configuration stored somewhere else now? Does anyone have a more up-to-date method for how to export the printable config?

Thanks very much!
