Database migration error


I migrate the old database to the new version by following this link:

But when run “cryosparcm start”, I have problem to start cryosparc with the following error:

Starting cryoSPARC System master process…
CryoSPARC is not already running.
database: started
command_core: started

500 Internal Server Error

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

command_vis: started
command_proxy: started
webapp: ERROR (spawn error)

When delete the migrate old database, cryosparc can be run correctly.

Any suggestion how to fix this?


More information about the above error:

  1. we update cryosparc from version 2.8 to version 2.11. cryosparc 2.8 was installed in one workstaion, but cryosparc 2.11 was installed in another workstation.

  2. we try to copy the old database generated by cryosparc 2.8 to cryosparc 2.11

  3. cryosparc 2.11 was running without problem, but the above error will appear when copy the old database to the new version.


Hi @michael99va,

You need to update the v2.8 instance to v2.11, then migrate it over. CryoSPARC v2.11 executes a database migration, more info here:
