I know Zone Director 3050 is consider End of Sale this year and the of the webpages indicated it's EOL Product. Recommend firmware is
10.1.1.0.55 (MR1 Refresh3) Not sure if they will have any more firmware after this since it's in the it's in the EOL product family.
To get that firmware you need to have a current support contract.
Depends on what features you use on the ZD Directory 3050
maybe Unleashed might work for you? but it's something to consider. However note unleashed only supports the max of 50 APs and 1024 concurrent connections.
check out the documentation of unleashed.
https://webresources.ruckuswireless.com/pdf/datasheets/ds-unleashed-portfolio.pdfCurrent Version of unleashed is 200.7.10.x released this year.. but I recommend sticking with 200.6.10.x since 200.7.10.x seems to have issues with iOS devices in terms of performance. If you go to unleashed all 46 APs R710 must be flashed... then program one of them to be a master and the other APs will automatically adopt as slave. Do note the R710 that acts as master can only have a max 100 of clients... the slaves can go greater than 100 which is no issue.
I think it would be easier and less work if you just pay for the support contract and get the firmware updated for ZD3000 to 10.1.1.0.55 . but maybe down the road consider unleashed if it can fit your needs but at least it's a consideration depending on what features you use on ZD.
