# How to determine a Cacti template version

Users are often bewildered when they are unable to import templates found on the forum and presented with the error, Error: XML: Hash version does not exist. Cacti prevents templates that have been exported on new versions back to older versions for compatibility. Quickly looking inside a XML template, it's not very clear how to determine what version it was created on. There IS a reason to the madness -- the hash!

Take the following example: `<hash_04**0018**258d1c9487a6c58dd804f4a012007664>` The first 2 digits are the type of the template. The next 4 digits are the Cacti version it was created on. The next 32 digits are a random number.

## List of Versions

    "0.8.4"  => "0000",
    "0.8.5"  => "0001",
    "0.8.5a" => "0002",
    "0.8.6"  => "0003",
    "0.8.6a" => "0004",
    "0.8.6b" => "0005",
    "0.8.6c" => "0006",
    "0.8.6d" => "0007",
    "0.8.6e" => "0008",
    "0.8.6f" => "0009",
    "0.8.6g" => "0010",
    "0.8.6h" => "0011",
    "0.8.6i" => "0012",
    "0.8.6j" => "0013",
    "0.8.7"  => "0014",
    "0.8.7a" => "0015",
    "0.8.7b" => "0016",
    "0.8.7c" => "0017",
    "0.8.7d" => "0018",
    "0.8.7e" => "0019",
    "0.8.7f" => "0020",
    "0.8.7g" => "0021",
    "0.8.7h" => "0022",
    "0.8.7i" => "0023",
    "0.8.8"  => "0024",
    "0.8.8a" => "0024"
