Replacing RB1000 with RB1100AH2

I’m trying to migrate a working RB1000 to a RB1100AH2. I’ve tried to copy the RB1000 RSC file to the RB1100 but it won’t take. I copied the 1000 config to the 1100 and cleaned up the interfaces on the 1100 and the router works all except for all the upload queues. How can I get from the 1000 to the 1100 and get everything to work as on the 1100 without having to redo all of my firewall rules and simple queues?

Which RouterOs versions are there on each?

5.26 vs 6.19. I suppose that may have been overlooked. You think it will be fine if I try with both configs same version?

It’s more likely though sometimes there are small errors easily spotted by doing

/import verbose=yes file-name=BackupFile.rsc

when importing the file
