Because of once more numerous changes by DMM an online update from v2.6.1 to v2.7 is not possible. So, image has to be reflashed.
We recommend to create a backup of your configs with our configurationsaver and restore your settings after flashing.
Support of our images is restricted to installation directly into flash because of well-known reasons.
Help for multiboot-systems are excluded from now on. Thank you for understanding this decision.
