I upgraded my nas machine which is based on nas4free this wednesday.
Everything went smooth. I made a backup of my current configuration. I uploaded the new
10.2.0.2.2332 image and after some minutes my server reboots automatically.
After this I was able to login. The upgrade procedure described to restore my previous configuration.
But this failed. The browser showed me the error
XML error: Not well-formed (invalid token) at line 1. I assume the encrypted version of my configuration can not be decrypted.
After reading some blog posts i found this one.
So i followed the steps described there to decrypt my configuration. With success. I decrypted my configuration with
openssl enc -aes-256-cbc -d -a -in <my-encrypted-config-file> -out decrypted-version.xml
I created an issue on the sourceforge bugtracker.
Restoring the decrypted configuration was no issue for nas4free. I was able to upgrade my nas4free machine to version 10.2.0.2 without any big issues.
