You don’t have to loose anything.
For the reminder, please check again dApp staking v3 & Tokenomics 2.0 docs.
Unbonding/unlocking period lasts for some time (e.g. 10 days).
Voting subperiod lasts for some time (not decided yet, will probably be longer than 10 days).
If you start the unlocking process at the beginning of the Voting subperiod, that gives you enough time to get the funds out, transfer them to another account, lock & stake. There’s no monetary loss here.
More information will be shared when it becomes available.
Zondax hasn’t yet shared any documentation about how the new generic & migration apps will work, and until then I cannot give any more comments about this.
