Hi there!

We recently received a case where user was facing below shown errors while upgrading from 7.3 SP3.1 to 2017SP3

One error in the logs was related to 'Solo'. 'Solo' was a feature that was discontinued in Sage CRM 7.2.
Other errors in the log indicated that the problem is on the Territory profile table, with the TPRO_ProfileID
You will need to check the IDs of the table and check that the correct IDs are referenced on the TerritoryPermissions table. If there are not then the foreign key linking to the TerritoryPermissions needs to be amended so that ever ID matches a valid Territory profile.
The issue is caused by an entry on TerritoryPermissions, where the UsrTProfileId did not match a TPro_ProfileID on TerritoryProfiles.

These SQL queries fixed the errors encountered:

SeaP_SearchBoxName like '%SoloProfileNewEntryBox%'
