Migrating TrueCrypt to VeraCrypt

According to your project description the VC storage format is incompatible with the TC format.
What is the best way to migrate a TC-encrypted non-system-volume to a VC-encrypted non-system-volume.
Guess: Decrypting the TC-volume and encrypting it using VC - right? Any short-cuts?
After re-encrypting should I delete TrueCrypt 7.1a from my computer or can it remain there without causing conflicts with VC? This could be necessary in case somebody sends me older TC-containers.
If you have a simply have volumes you can create a new volume with VeraCrypt and then copy the contents of the Truecrypt volume to the VeraCrypt volume.
If you have WDE then decrypt the entire disk and then re-encrypt with VeraCrypt. However I suggest you wait a little while until the new release of VeraCrypt is out.
Yes, you can leave Truecrypt on your system.
Just to confirm the answers given previously and that there are no conflicts between TrueCrypt and VeraCrypt.
A conversion tool from TrueCrypt 7.x non-system volumes to VeraCrypt is planned but we are not sure if it will make it to the next release.
Do I have to actually generate a new Veracrypt volume to get all the security improvements? Or can I just change the password and/or header key derivation algorithm on a TrueCrypt volume?
Potential unreported failures in random collection were one of the things found in the TC audit, right?

Thanx a lot. Just one more question: what is WDE?
WDE means Whole Disk Encryption. It can also be refereed as FDE (Full Disk Encryption).
Seeing as this topic comes up high when searching for migration from TrueCrypt, I'd like to ask here... when using ordinary TrueCrypt volumes and migrating to VeraCrypt, I know I can just change the password and/or header key derivation algorithm to migrate to VeraCrypt. But is doing this sufficient to solve all of the "security weaknesses" in TrueCrypt that have been fixed in VeraCrypt? Or do I have to actually generate a new volume from scratch?

There is no change to the encryption algorithms between TrueCrypt and VeraCrypt. The difference is the number of iterations performed for the header key in VeraCrypt. Hence, you only need to change the password and/or hash of the TrueCrypt volume to get the VeraCrypt improvements of the higher iterations.
