We have Server running with SQL 2008 SP2.
Need to implement High Availability for Server, I have another Server with SQL 2012 Installed.
We don't have SAN or other shared storage. so Always on is only option.
my questions are:
1- Upgrading SQL 2008 Sp2 to SQL 2012 Requires any kind of Down time ? It can be done while server is running?
2- For Always ON HA What are Steps?
