From: David Garcia Date: Thu, 22 Oct 2020 08:50:56 +0000 (+0200) Subject: Fix bug 1263 X-Git-Tag: release-v9.0-start~9 X-Git-Url: https://osm.etsi.org/gitweb/?a=commitdiff_plain;h=refs%2Fchanges%2F02%2F9902%2F1;p=osm%2FN2VC.git Fix bug 1263 Update database endpoints when a new VCA_HOST_IP is provided Before, we were not considering the that the VCA_HOST_IP could be updated, in that case, the old ips stored in the database should be replace by the new one. Of course, this won't do any model migration from the previous VCA to the new one. It will only start pointing to the new VCA provided.
