Absolutely. Removing the crypto map from the interface drops all tunnels immediately.
Adding back in right away, most tunnels will re-establish immediately and almost nobody will even notice.

But if you are using version 6.3(4) and UP, you can do any changes to the VPN without disabling the crypto map applied in the interface. Otherwise you will stuck your firewall.

But there is some special cases where you need to turn off the crypto map service and start it again, when you do changes. I mean no crypto map and no isakmp and then crypto map and  isakmp

I had a vpn setup in this pix, the remote site changed IP addresses and key. I changed
(config)# tunnel-group <peer IP> ipsec-attributes
pre-shared-key <new key>
transform-set  
isakmp policy 40 encryption aes-256
isakmp policy 40 hash md5
access-list outside_cryptomap_40 extended permit ip 192.168.233.0 255.255.255.0 172.16.0.0 255.255.0.0
What else should i check/change?
Now I can not get the tunnel up, this is pix V7.0 to checkpoint, i had this working with a test pix.
