I’m about to start a long and tortruous journey.
I want to delete a sbs2008 server in a new company joined the group!
There are:
- domain active directories
- shared folders
- mailboxes
- pop3 connectors
- remote access to exchange
The situation is this:
- about 20 clients joined in the domain AD
- microsoft outlook configured with local exchange
- home directories containing some pst with mail archives and calendars
- exchange every 15 minutes downloads mail from pop3 external server on Register
- the clients send mail directly with public IP of the router
- current server is a hp proliant with 32gb of ram, raid 5 200gb + raid 5 500gb, 1 network card.
obviously all on the fly, maybe a Saturday and Sunday (too optimistic? )
the steps I’m preparing in my head are:
- buy new server ( tower dell, single socket, 32gb, raid 5 3x1tb, 2 network card)
- install nethserver, AD + Webtop5 + mail2-*
2.1 Request Let’s Encrypt Certificate - create AD domain “publicdomain.it” (actually is publicdomain.local)
- re-create all user
- sync existing inbox, then disable pop3connector on Exchange Server
- convert OST to PST (you know this? https://gallery.technet.microsoft.com/office/Free-Tool-to-Convert-OST-adfb7c69) or via import export of outlook? what do you recommend?
- copy per client PST (ost converted and archive) on new personal home directory and import in webtop user via http://docs.nethserver.org/es/v7/webtop5.html#importing-from-outlook-pst
- enable pop3connector on NS
- re-create all folder and copy file
- insert in external DNS, TXT DKIM and TXT v=spf1 a mx ip4:EXTERNALIPADDRESS
- rejoin all machine in new domain with https://www.forensit.com/domain-migration.html ( i have used it in past for conversion of local user to domain NS user )
the big doubts are:
- I can add the new account in outlook, by performing the add-on account exchange procedure, pointing to the new NS server? (So far I’ve only tried to add the account on android)
- for access from outside I only create the nat of port 443, as currently set with exchange?
- instead of using the pop3 connector, imposed as the primary smtp server directly on the NS server, or is it a useless risk?
I forgot something?
