Hi, I'm back with my paper about Migration a Windows company to *nix. I'm now choosing the replacement software for the Windows equivalents. Are there other/beter options ? I would like to have some feedback, on my choices.

Try the filesharing facilities of Samba instead - works very nicely in the company I work for. > Server F > > NT4 Webserver IIS > > Apache - php/perl What language is currently used for CGI applications? If it's ASP (VBScript), you may need an ASP environment for Linux. There is one at http://developers.sun.com/prodtech/asp/ (formerly Chilli!soft) http://wwws.sun.com/software/chilisoft/ There is also a converter for VBScript ASP pages into PHP: http://asp2php.naken.cc/ Same for server G. > Server H > > NT4 Database SQL > > Oracle (large) mysql > (small) If you really insist on using a commercial (expensive) database, use IBM's DB2 Universal Database. It is more modern, better scalable, faster, more reliable, has better support and is cheaper! I have worked with both databases, and I won't touch Oracle any more! For a small database, you may want to look at Firebird, because unlike MySQL this free database has all the neat features of a *real* database (stored procedures, triggers, real transactions, subselects...). Very convenient once you get used to it... > Server J > > NT4 Mail / Groupware > Exchange > > OpenGroupWare > > Suse OpenEchange server Depending on your needs, you may want to use IBM's Lotus Notes/Domino server instead. It's not cheap, but much more reliable - and IMHO the best groupware available. You can model all your business structures and workflows in Notes - if one step is done, the next in the row gets an e-Mail with link to the process. Client and server are available for Linux. > Server K > > NT4 Mail relay > > Postfix Shouldn't this be integrated into server J? > Server M > > NT4 Proxy > > Squid Should be moved onto server L (firewall) I hope that helps.

I would migrate the servers first? then use Samba until the workstations are migrate also. After that i would use LDAP for passwd and others. But that is a mail for part 3 Thanks for your feedback Martin Patrick --=20 Insufficient facts always invite danger. -- Spock, "Space Seed", stardate 3141.9 PGP Key: http://users.pandora.be/rivendell/marquetp.gpg Fingerprint =3D 2792 057F C445 9486 F932 3AEA D3A3 1B0C 1059 273B ICQ# 316932703=20 Registered Linux User #44550 http://counter.li.org |
