My bad, sorry.

I forgot in my previous message : all users have system accounts,
delivery is to be done (it works fine already) to their home directory's
Maildir/ subdirectory, in the Maildir format. The location of their home
directory is retrieved from LDAP using the configuration sent previously.

OK so with my actual configuration routing and delivery are correct in
these directions :
Not migrated yet users :
Internet => MX => Server1 => Backend1
Backend1 => Server1 => Internet
Migrated users :
Internet => MX => Server1 => Backend2
Now I want to have this :
Backend2 => Server1 => Internet
For each migrated user, i.e. who utilises Backend2 as his MUA's SMTP
server, even if destination email address is in the already migrated
group.

Not sure how to do this because in the future (that's why I didn't talk
about this) the Server1 => Backend2 connection will be done through a
load balancer (there will be several servers to host the 'Backend2'
role). So I don't want fixed associations between a migrated user and a
particular "Backend2" server.

Not always : not when receiving messages from Server1 using its
transport map.
This only has to be done (message forwarded to Server1 for routing) when
sending messages from Backend2 when Backend2 is used as the outgoing
SMTP server in a migrated user MUA's preferences.
But I don't know how to differentiate between these two situations in
Postfix configuration :-(
Thanks in advance for any help
