I think i found out…
We have to check every resource and check if the following line is in the __resources.lua file :
resource_manifest_version ‘< manifest >’
Since the upgrade, if no manifest is set, it uses the new one : "44febabe-d386-4d18-afbe-5e627f4af937"
Before the upgrade, it used to use “f15e72ec-3972-4fe4-9c7d-afc5394ae207”
We have to check every resource not specifying any manifest and add the following line to make sure it uses the previous one. (Then debug to use the new one)

Does it seem logical and possible?
By default, no manifest version is used, which is equivalent to manifest GUID 00000000-0000-0000-0000-000000000000. This (along with the empty GUID) will be removed in FXServer, and resources will be required to specify a manifest version.
