We will be upgrading multiple SNA 4.0 domains to Host Integration Server. Our plan is to upgrade all NT 4.0 server to Windows 2000 first and then Upgrade to HIS. If we resolve printing issues with SNA 4.0 running under Windows 2000 then can we expect that printing will work as well on HIS since it is running on 2000. Any feedback would be appreciated. I very nervous about this upgrade but hope that HIS will be more stable than SNA 4.0. Does anyone have suggestions for upgrading SNA 4.0 to HIS?
