The version of cacti which I'm using is 0.8.6k
it was checked out from svn sometimes ago
When I want to upgrade to recent stable version 0.8.7,
it was said not supported!!
What should I do now?
pls

Who told you that?

Anyway, it is a three step process.

• Turn off HTTPD
• Disable Cron
• Backup your database.
• Get all the new files (including a few patches on the forum)
• Install the files, remember the "include/config_*.php" files are obsolete
• Edit the "install/0_8_6j_to_0_8_7.php" file and remove the inserting of the 1 minute RRA. It is well documented in that script.
• Run the following sql code
  Code:
  update version set cacti='0.8.6j" where cacti='0.8.6k'
• Re-enable HTTPD
• Refresh your browser
• Confirm the upgrade script worked well. If you get any errors, you may have to hand apply some database changes. Look at the upgrade script for more details
• After all is well with the database, re-enable cron

So, since we don't want to have to tell this to all users, I guess that is why somebody, and I know who he is, probably told you it's not supported. My comment is thanks for helping us test
