I made a VM and started testing version to version upgrades starting at 7.1.3 and stepping through different versions, reverting to my snapshot between each upgrade. What i found is this... And it's still broken even from 7.2.1 to 7.5.0 (latest beta).
I can reproduce this on every version starting with 7.1.3 (didn't go back any further).
Fresh new FTP Task created for each version i started with (VM Snapshot was made at this point), then upgraded or downgraded to the listed versions, and it always gets reset to / no matter what. I tried WAY more than what's listed, but this is the list i did twice just to be sure. 7.5.0 used for my testing is build 14795 built today, 10-20-2014.
7.1.3 --> 7.1.4 (remote file filter path was reset)
7.1.3 --> 7.1.5 (remote file filter path was reset)
7.1.3 --> 7.1.6 (remote file filter path was reset)
7.1.3 --> 7.2.1 (remote file filter path was reset)
7.1.4 --> 7.1.8 (remote file filter path was reset)
7.2.1 --> 7.1.8 (remote file filter path was reset)
7.2.1 --> 7.1.9 (remote file filter path was reset)
7.2.1 --> 7.5.0 (remote file filter path was reset)
However, if we create a new task like above, upgrade or downgrade to any version... the path does get reset to a / that first time. But after the upgrade/downgrade if we adjust the download path now, and upgrade or downgrade to any other version, it'll now keep the path information that was set.
So, to reproduce. Pick your versions, it won't matter... but for my test I did at least 8 different combinations. This is the one i'll document:
1. New FTP Download Task Created on version 7.1.8, folder path set to /Folder718
2. Upgrade 7.1.8 to 7.1.9, folder path was reset to /
3. Fix folder path on existing ftp download task using version 7.1.9 and set path to /Folder719
4. Upgrade 7.1.9 to 7.2.1, folder path is NOT reset to /, everything worked as it should and the path is still /Folder719
Now, I could've gone from 7.1.9 to 7.1.3, 7.1.9 to 7.5.0, 7.1.9 to 7.2.1, etc.... and it would've all been fine at this point.
If I were to delete that task (or really, just the download 'ftp command' inside the task with the pathing in it) and re-create it, ANY version i upgrade/downgrade to at that point will be broken and reset back to / again.
Hopefully that makes sense. New Task/info, upgrade/downgrade resets path to /. If it's already been through one upgrade at some point, it's good. :)
So, the concern would be any FTP tasks that you've added since the last time you upgraded. Older tasks won't get reset, just ones that haven't been through an upgrade haha.
