Using brspace (tbreorg), you can achieve this.
This is what where you perform the actual compression, I gave my source and target within the command line which migrated my data from old TS to new TS with compression option ON.
Ex. Command: brspace -u / -f tbreorg -a long2lob -s <Source TS> -t allsel -n <Target TS> -I <Target Index TS> -c ctablobind -lc medium -ic sap_proc -l 2 -p 16 -SCT -KST
