zd1100 with zf7372 Upgrade question

[dicky_siu]

Hi, I have a ZD1100 (version: 9.6.1.0 build 15) which controls 7  ZF7372 APs (version: 9.6.1.0.15) in my environment.
If I upgrade the ZD1100 to version 9.8.3.0.14 (MR3), will the 7 ZF7372 APs automatically upgrade to version 9.8.3.0.14 accordingly?
I have no experience on upgrading the ZD firmware, please help, thanks. ^^

Thanks Michael 's information. I will do the backup before upgrade.
