Configuration from user mode not compatible with service mode?

Can I use configuration from user mode via export and import to service mode?

my trials did not work

Please clarify “did not work”. Did import work? Did Database tab pick a reasonable spot for service?
Beware that the default service install uses SYSTEM user profile, and Windows upgrades destroy it.
SMB shares as a service (especially SYSTEM) are trouble. How far are you able to get things going?
