Updates / Release notes
For details on the updates and changes in individual builds, see release notes.
Updating from an earlier v. 2.x build?
Simply download and install above to the same location on your harddisk as the older build.
IMPORTANT: Always make sure to backup your settings and data before updating.
Upgrading from v. 1.x ?
Simple Failover v. 2.x cannot be installed on the same computer as v. 1.x (at least not within the same Windows installation),
because v. 2.x requires Windows Vista / Server 2008 or later and v. 1.x requires an earlier Windows version.
Simple Failover v. 2.x cannot directly use a configuration file from v. 1.x, because v. 2.x uses a configuration file in JSON format, where as v.1.x uses a configuration file in XML format.
However Simple Failover v. 2.x does include a tool which can convert a v. 1.x configration file into a v. 2.x configuration file.
To use this, run "v1upgrade.exe" found in the directory where Simple Failover v. 2.x is installed.
Also before upgrading, make sure to check the list of retired features and breaking changes in Simple Failover v. 2.0
