No, because the CC licenses have an explicit provision that allows it |
6 |
when distributing a modified work (which they call an "Adaptation", |
7 |
defined in section 1a). |

For example, CC-BY-SA-3.0 says in section 4b: |

|
11 |
You may Distribute or Publicly Perform an Adaptation only under the |
12 |
terms of: (i) this License; (ii) a later version of this License with |
13 |
the same License Elements as this License; (iii) a Creative Commons |
14 |
jurisdiction license (either this or a later license version) that |
15 |
contains the same License Elements as this License (e.g., |
16 |
Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible |
17 |
License. [...] |

Item (ii) is what gives us the right to distribute under CC-BY-SA-4.0. |
