Hi,  
I’m running a canton domain and trying to upgrade it to 2.6. Here is the steps I’m going through.

1. Download 2.6 binary
2. Shut down the 2.5.2 sequencer, mediator and manager.
3. Start the sequencer with 2.6 binary in manual mode

`java -jar ~/development/cantonEE/sdk-2.6.0/canton/canton.jar daemon -c share-db.conf,domain-seq.conf --manual-start`

I got the following error and cannot proceed.

```haskell
2023-03-30 14:31:45,815 [main] ERROR c.digitalasset.canton.ServerRunner - Canton startup encountered problems:
2023-03-30 14:31:45,816 [main] ERROR c.digitalasset.canton.ServerRunner - - failed to initialize sequencer1: There are 1 pending migrations to get to database schema version 5. Currently on version 4.

```

Anyone know what is missing there? Thanks.

Hi Frank,

Just checking if you have completed the migration of db? Some documentation is available here :

Thank @rohitt , I found the issue. For upgrade/db migrate, deamon mode does not work with --manual-start. It will not open the console.
