Hi, 1. I have a Firebird-2.5.4.26856_0_Win32 database which I backed up (using Flamerobin) after renaming RDB$FIELD_NAME field values in the system table RDB$FIELDS of the source database as under: 'SEC$USER_NAME' to 'SEC$USER_NAME_RAJIV' 'SEC$NAME_PART' to 'SEC$NAME_PART_RAJIV'
2. I installed Firebird-3.0.0.32136_0_Win32_RC1 on Windows 10 with the Security DB initialized for Legacy Authentication. Using Flamerobin, I registered Server and then registered the EMPLOYEE.FDB. 3. Then I restored the backed up FB 2.5.4 file. 4. The Flamerobin connects to the FB 3.0 restored file but my .NET application (Provider .NET 4.8.1.1) reports the following error : FirebirdSql.Data.Common.IscException: I/O error during "CreateFile (open)" operation for file "D:\HMS\APPHMS\HMSFIREBIRD\HMS.FDB" 5. Please help. Thanks and regards, Rajiv
