SAP Data File size considerably reduced after Unicode Conversion


Hello Experts

I have just performed a CUUC (Upgrade along with unicode conversion) from R/3 4.7 to ECC 6.0 EHP5. The data size that i earlier had was close to 463 GB (MSSQL MDF, LDF Files), after the data export to be converted to unicode the size was 45 GB (10% of actual data size, i feel this is normal after heterogeneous system copy), but after the import again the DATA file size is only 247 GB, is this normal ? or have i lost some data ? For ex, I tried checking tables like MSEG and the number of entries have reduced from 15,678,790 to 15,290,545.

Could you kindly let me know if there is a way to check from Basis perspective if i have not lost any data ? I have followed all the procedures as per SAP Standards.

Waiting for your quick reply.

Best Regards
