About changing the license from GPLv3 to AGPLv3

[Finjon Kiang]

Recently, an accounting software, FrontAccounting(
http://frontaccounting.net/ ), decided to change their license from
GPLv2 to AGPLv3.

http://frontaccounting.net/wb3/pages/posts/new-license-type-gnu-agpl-from-release-2.166.php

In the forum, they said they said(
http://frontaccounting.net/punbb/viewtopic.php?id=398 ):

"We have got a permission from the author of OpenAccounting to
increase the license to GPL v.3. OA was discontinued back in 2005. And
the GPL v3 and AGPL v.3 are compatible, so there should be no problems
by using the license GNU AGPL v.3 (or later) for FA."

FrontAccounting was extended by OpenAccounting, and OpenAccounting was
extended by WebERP. Both WebERP and OpenAccounting were released under
GPLv2.

According to the FAQ in gnu.org:
http://www.gnu.org/licenses/gpl-faq.html#WhatIsCompatible

In my understanding, the word 'compatible' means the programs which
released under either GPLv3 or AGPLv3 could put together. It doesn't
mean anyone could change the licenses of either program between GPLv3
and AGPLv3.
