from my point of view a general guide will be impossible because of there are to many different scenarios …
Some of my thoughts about a migration:
Migration scenario from running Zentyal server to a new Nethserver (maybe to a virtualized machine or complete new independend hardware)
which services running under zentyal, are available under Nethserver too all?
transferring users, groups, file shares, ACLs etc… we have to solve the problem with samba 4 integrated ldap (Zentyal) and openldap - how can we automate the migration of domains, users, groups, file shares and ACLs, email accounts etc. .
That means the whole infrastructure and services without data (the metadata)
automated file sync maybe from Zentyal duplicity backup, setting the right, new ACLs on Nethserver
automated syncing the e-mail accounts with imap sync
groupware data can only be synced easily by sogo-tool [link] http://wiki.sogo.nu/backupRestore [/link]
what’s about the jabber chat histories ?
Proxy server filter with filter rules
Network infra structure: networks, interfaces, gateways, network objects, dhcp …
Maybe we should focus on 2., 3., 4. and 6. !
Automating the migration of the network infrastrucure, firewall etc. is to complex…
This are only my thoughts about a migration from Z. to Nethserver. Maybe somebody have additional hints or maybe some solutions.
with warm regards
