I noticed there is a problem with dumpwallet option. It does not seem to dump segwit addresses ("3"), and dumps only the standard one ("1"). Is it a bug or work as intended? How can I perform full dump of an wallet then?

Currently dumpwallet only dumps private keys, not scripts. This will be fixed by #11667, which adds scripts to the dumpfile and supports importing them again with the importwallet RPC.
Note that until then, you still technically have backed up your segwit addresses too, because from the private key you can recreate the P2SH-P2PKH address starting with a '3', it just isn't as easy as using importwallet.

@MeshCollider ok I understand. If I
dumpwalletand receive all my standard addresses, thenimportwalleton another bitcoin core and write a script that for each "1" address calls "addwitnessaddress" to generate a Segwit one - can I be certain that theses addresses will be the same I used before? Can I workaround migrating seegwit addreses that way? -

@khelle yes I believe that is currently the case

@MeshCollider I just tested it and it works. Thank you for your guidance.
