Problem in restoring various session

[n_lona]

these following restore files are different session in cracking my router root account (damned isp). Is is simple to restore session made in different version by simply switching number version of oclhashcat binary. Is it true or false?

Code:

�/home/hpY P�6./oclHashcat-1.37/oclHashcat64.bin -m 1800 -a 3 -o found -i --increment-min 7 --increment-max 18 --force admin.hash ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a

Code:

�/home/hpw           ����./oclHashcat-1.36/oclHashcat64.bin -m 1800 -a 3 -o found -i --increment-min 7 --increment-max 18 --force admin.hash ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a

why these following session cannot be restored with the command oclHashcatx.bin --restore --session (session_name) ? eg.: ocdHashcat64.bin --restore --session 12char/8char/oclHashcat12char

Code:

�/home/hp �r
./oclHashcat-1.36/oclHashcat64.bin -m 1800 -a 3 -o found.txt -i --increment-min 12 --increment-max 18 --force --session 12char admin.hash ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a

Code:

�/home/hpR           �I?
./oclHashcat-1.36/oclHashcat64.bin -m 1800 -a 3 -o found.txt -i --increment-min 8 --increment-max 18 --force --session 8char admin.hash ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a

Code:

�/home/hp�           �f./oclHashcat-1.37/oclHashcat64.bin -m 1800 -a 3 -o found.txt -i --increment-min 12 --increment-max 18 --force --session oclHashcat12char admin.hash ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a
