Only way I could fix this issue was by deleting the migrated VM and restoring and re-registering a backup VM machine. I would however like to migrate to sp6 just to be fully patched and secure. Other GroupWise installations run fine with sp6 and had no conflict. Not gms.

Three possible conflicts were identified during migration. I thought I copied the conflict messages, but copy did not save. Had something to do with libraries and python. I stupidly chose to update thinking the CE 24.3 was likely built to tolerate newest security. Wrong. Probably broke something. I suspect it might have something to do with cyrptography.

If I run pip list | grep cryptography
it reports that I am running 41.0.3

The Dashboard error says:
ERROR: Cannot validate GroupWise maintenance. GroupWise maintenance status: Unknown. Services are stopped. To resume service, fix the GroupWise maintenance issue.
Device Sync Agent shows starting
Groupwise Sync Agent shows stopped.

If I try to reinstall gms CE 24.3 I get:

Using -iter or -pbkdf2 would be better.
bad decrypt
4067C4B4C27F0000:error:1C800064:Provider routines:ossl_cipher_unpadblock:bad decrypt:providers/implementations/ciphers/ciphercommon_block.c:129:
Failed to verify GW Admin App settings

The install also asks for Password for user datasync_user: 

But despite entering the correct password, the install can't get past the password request.

I opened a tech support issue, but no help whatsoever.

I suppose I can backup restored VM, and try migrating again and choose to keep all the conflicts and see what happens.

Any suggestions?
