Upgrade from 6 to 7 fails

I’m trying to upgrade from 6.2.1.122 to 7.

When I clicked on the upgrade notification in admin Overview, I see a page with no options. No upgrades or downgrades available!

I used the updateold workaround here and was able to update to 6.2.5.48

I tried once again to update to 7, this time it was available on the update page however, after spinning for about 10 seconds, I was brought back to the login page and on logging in, I was still at 6.2.5.48.

I then applied the latest snapshot 6.2.7.0 and tried again to upgrade to 7 and that completely borked my install with the error

you cannot instantiate the interface [zip:///opt/lucee/tomcat/lucee-server/context/context/lucee-admin.lar!/Application.cfc] as a component (application_cfc$cffalse)

Fortunately, this is on proxmox and I was able to restore the vm from last night’s backup but I still want to be able to move to 7

Any ideas what’s blocking me?

From what I understand, Lucee 7 is set to run on Jakarta. Lucee 6 runs on Javax. There was a time where Lucee 7 could run on JavaX, but I think that is gone. And even so, you would have had to manually configure Lucee 7 to use JavaX.

The Lucee 7 new features docs recommend a clean install.
