To copy and convert data from BTRV files into c-treeRTG, use ctmigra as shown below:
Windows x86
ctmigra.exe btrv –s WBTRV32.DLL S:\Data.PSQL\MYFILE D:\Data.RTG\MYFILE.dat
Windows x64
ctmigra.exe btrv –s w64btrv.dll S:\Data.PSQL\MYFILE D:\Data.RTG\MYFILE.dat
Unix/Linux
./ctmigra btrv –s libpsqlmif.so /data.psql/myfile /data.rtg/myfile.dat

Note: This example can be useful for Btrieve users as well as COBOL users.
To copy and covert data from Micro Focus COBOL tables into c-treeRTG, use ctmigra as follows:
ctmigra extfh -s C:\MICROFOCUS\lib\MFFH.DLL!MFFH S:\Data.MF\MYFILE D:\Data.RTG\MYFILE.dat
To use ctmigra with Unix-based Micro Focus libraries, be sure to pre-load them with the LD_PRELOAD environment variable or an alternative mechanism.
For example, on an AIX 64-bit platform (this is all on a single command line):
LDR_PRELOAD64=libcobrts64.3.so:libcobcrtn64.3.so:libcobmisc64.3.so ctmigra extfh -s libcobrts64.3.so!EXTFH /data/mf/myfile /data/rtg/myfile.dat
For example, on a Linux 32-bit platform (this is all on a single command line):
LD_PRELOAD=libcobrts.so:libcobcrtn.so:libcobmisc.so ctmigra extfh -s libcobrts.so!EXTFH /data/mf/myfile /data/rtg/myfile.dat
