I use KWallet with a custom wallet to store an encrypted list of secret passwords. After upgrade to openSUSE Tumbleweed which brought the latest Plasma5 I noticed that my custom wallet disappeared. I was just about to report a bug when I found out the solution which I document here: 1) Kill kwalletd5 (that prevented the old .kwl files to be loaded) 2) Open the old kwalletmanager (which accesses the path ~/.kde4/share/apps/kwallet/ which contains the custom .kwl files) 3a) KWallet(4) now shows the original list of password storages 3b) Open the custom storage, copy contents to clipboard 4) Open kwalletmanager5, create a new password storage (which is now stored in ~/.local/share/kwalletd/) and paste content. I wonder if this migration was supposed to work automatically without the described intervention.
