I have a Synology DS431j device running on DSM 4.3-3810 version. This device is part of an AD and acts primarily as a file server. Beside, it offers FTP and EMAIL services. The DSM 4.3-3810 version is rather old and the device asks for upgrade to the newest 5.0 version. My question is if anyone has performed this upgrade running these services (fileserver, ftp and email) and after upgrade was all ok. I fear that these services might get faulty after the upgrade.
As a remark, I have another DS431j that servers only as backup station, for this device I have made the upgrade and all went ok.
Thank you and regards,
