save ended life of zf_7762

[alexey_isakov]

I have a ZD1200-spot whith a lot of R500 and just two zf7762 (old but working good).

zf7762 are "End of Software" till 2015 (9.12.ХХ is latest ver for this APs), "End of Life" till 2018 and cetera, sad RUCKUS

Does anyone explain me,

Is there some procedure #Move EOL AP to the Staging Zone# onto ZD like SZ (but not SZ)? 
Can I migrate zf7762 onto SZ cluster(3.5.1.0.862)? (ZD-->SZ Migration procedure 9.13 or newer announced, sad RUCKUS)
What kind of service impact will happened in case if I would upgrade ZD sw to the newest version (9.12.3.0_75---->10.1.1.0_42)?

VARIANTS:

- NO upgrade will be permitted by GUI due to zf7762 in pool;
- R500 became newest and zf7762 will LOST on the system (in ZD GUI) absolutly, include MESH links;
- R500 became newest and zf7762 will not LOST on the system (in ZD GUI), they still working/associate new clients but whithout resolved issues;
- R500 became newest and zf7762 will not LOST on the system (in ZD GUI), they still working whith associated clients but not will be able to associate new clients;
- zf7762 will be work in Stand-Alone mode;
- all points will be lost becouse they are all in one DEFAULT groupe whith zf7762;
- smth ELSE maybe;
