Thanks that makes statement makes it much clearer now.

I think that https://wiki2.dovecot.org/Migration/Dsync docs could be improved to clarify that the migration is using the imapc/pop3c mailbox types with links to https://wiki.dovecot.org/MailboxFormat/imapc and https://wiki.dovecot.org/MailboxFormat/pop3c (this is another bug as the link from https://wiki.dovecot.org/MailboxFormat for pop3c takes me to "This page does not exist yet. You can create a new empty page, or use one of the page templates." )

In https://wiki2.dovecot.org/Tools/Doveadm/Sync#section_arguments the destination list 5 possible options for the destination

but in the page on migration https://wiki2.dovecot.org/Migration/Dsync it seems to use a sixth undocumented "imapc:" option for destination

e.g.

doveadm -o mail_fsync=never backup -R -u user@domain imapc:

"imapc:" is also referenced on https://wiki2.dovecot.org/Migration/Gmail

Is https://wiki2.dovecot.org/Tools/Doveadm/Sync#section_arguments missing this option?

imapc falls under the first option, "location".
