Description Petr Hracek 2015-03-05 12:55:11 UTC

Description of problem:
Before alone upgrade done be redhat-upgrade-tool. preupgrade script should detect if redhat-upgrade-tool is executed with proper target version.
If not then upgrade should fail.

Question is if this can be done directly in redhat-upgrade-tool so that we will save time before downloading packages.
I think that redhat-upgrade-tool can detect if version file (generated by preupgrade-assistant-contents) exits and then compare them with command line arguments.
Use cases:

1) If version file doesn't exist then upgrade will stop and doesn't continue.
2) If version file contains version 7.1 then redhat-upgrade-tool should have arguments with 7.1 version too and upgrade continues.
3) If version file contains version 7.1 and redhat-upgrade-tool arguments are  with 7.0 version then it have to stop as well.
4) If version file contains version 7.0 and redhat-upgrade-tool contains 7.1 then upgrade won't be possible too.

I think that this is a good part for redhat-upgrade-tool.

What do you think?
