oh thanks,
so i dont allow my old wallet to sync? i opened it firstly ofc to check it was working and its way behind, i did a wallet backup and close it
i do the mandatory update as usual i guess and after that i sync? or i have to delete my old datachain too? i saw people is downloading the whole chain
i prefer to solve my doubts before to screw something more lol
btw the exchange sites are updated i guess too, nothing to do there? i have not checked my dnr left there lol hope they are well

Fastest way is to download chain-data and just sync from that point because syncing is little slow in this wallet version.
