CTP 3.0 is preview software. It is not publicly supported for operations. Customers who are in the SQL Early Adopter Program, may have support to run SQL Server 2019 CTP 3.0 by special agreement, in consultation with Microsoft. For CTP 3.0, this support includes:
- Side-by-side installation. SQL Server 2019 CTP 3.0 supports side-by-side installation with instances of SQL Server 2012 through SQL Server 2017, or other instances SQL Server 2019 CTP 3.0.
[!NOTE] While side-by-side is not blocked with SQL Server 2008 and 2008 R2, there are no commonly supported Windows Operating system versions between them and SQL Server 2019.
- SQL Server 2019 CTP 3.0 supports in-place upgrade from instances of SQL Server 2012 through SQL Server 2017. Upgrade from a previously released SQL Server 2019 CTP release to CTP 3.0 is not supported, a new installation must be performed.
