问题
I'm trying to restore an very old code of mine, in that time the database was ms access and then I upgraded to SQL Server 7 SP4, now I want to restore those old backup, but SQL Server 2014 does not allow this..
So I would like to know how can I get to restore those backup, without installing SQL Server 7 ..
Thx U
回答1:
It's a 'three-version' rule. For example, to SQL Server 2012 one can only restore databases from 2008R2, 2008 and 2005 versions. Similarly, SQL Server 7 database can be restored to 2005, but no later version. To restore it to 2014, you will (by the rule) have to restore it to 2005, take a backup on 2005 and restore it to 2012, and only then 2012 backup restore to 2014. However, there is an exception: 2014 acknowledges the 2005 SP4, so you can skip the second step, and restore straight from 2005 to 2014 (but only from 2005 SP4).
