For more information about the migration of projects see section "Migration".
Note
WinCC user no longer needs to be a member of the "SQLServerMSSQLUser$<COMPUTER
NAME>$WINCC" user group
When you migrate projects created prior to WinCC V7.2, you remove the WinCC users from
this group.
In WinCC projects prior to V7.2, you will find the user group under the name
"SQLServer2005MSSQLUser$<COMPUTER NAME>$WINCC".
Notes on licensing
You need to upgrade licenses of WinCC prior to V7.4 to the current version.
You can update the licensing retroactively. Detailed information is available in the WinCC
Information System under the topic "Licensing".
