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
