Hi,
I wanted to ask you about the process of data migration from NAVISION 2013 to NAVISION 2018, since once I have passed step number 11, the following guide
https://docs.microsoft.com/en-us/dynamics-nav/upgrading-the-data, and I execute the synchronization of the data schema, I get the following error:
![4w4irglu5fcb.png](https://us.v-cdn.net/5022383/uploads/editor/bb/4w4irglu5fcb.png)
The translated message is as follows: "The 'default' subscriber can not be accessed".
I have tried with the access permissions to the BD, I have repeated the migration process several times, but there is no way to overcome this step.
Thank you very much in advance.
Sergi.

"The tenant 'default' can not be accessed".
It looks like you have created or have a multi-tenant installation. If it is the case I think you may need to mount your default tenant before accessing it.

We didn't set up the multi-tenant option. Could this be a problem that comes from the insatlation of NAV 2018? Would you recommend re-installing NAV 2018?
We are upgrading from 2009 how could it have converted to multi-tenant?
Thanks in advance.
Maybe you have installed the NAV2018 ib Multi-Tenancy mode somehow when you performed step 6?

NAv2017, Cumulative Update 13, KB 233463 : The "The tenant 'default' was not found" error is shown when you try to migrate tenants from Dynamics NAV 2016 to Dynamics NAV 2017 by mounting them.
So perhaps this is some sort of bug and the CU1 for 2018 will fix it
