Update from 5.2 to 6.1.1 - no free space

[Tommi]

Hi, I'm running on old loader and 5.2 FW, I would like to go to 6.1.1 on the newest loader, It boots up correctly, recognize that I have disks from old device and ask to migrate.

I want to migrate and keep all data however it states that there is no free disk space  can you help what to check? I do not find any topics with this issue.

I'm running Synology Hybrid Raid if this is important, double 3T drives and 2T still available,

I've not experienced this error but it might be because of your SATA settings (AHCI/IDE etc). I would try a migration/upgrade to 6.0.2 loader/DSM first which might be an easier process as the jump in boot loader/DSM versions is lower so less chance of compatibility/architecture changes. Make sure you have all your data backed up whatever you do.
