Big thanks for the reply! But no, I can't ping the diskstation after reboot in normal mode. Only if I choose "reinstall" mode in loader menu. So this shouldn't be the issue right? Or do I need to check this although?

I have set up a newer NAS working and running with DSM_DS3615xs_23739. Now I tried to migrate my two old hdds from my old custom built running 5.2.something. Connected and choose "Migrate" with Synology Assistant, clicked manual and choose the DSM_DS3615xs_23739.pat file. After reboot the system won't startup anymore. Any suggestions? Tried reboot a couple times but nothing... Also tried choosing "reinstall" option with bootloader and then I found the diskstation again with "Migrate" option. Did same procedure but no good this time either. Tried to search around other posts but didn't find any solution Thankful for all help
