将新版本到处的cacti模板导入到旧版本的时候，就会报Error: XML: Hash version does not exist.，解决的办法是修改xml里面的相关hash值就可以了。
以下是cacti xml hash的一些说明：
Take the following example: <hash_040018258d1c9487a6c58dd804f4a012007664>
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"
For the example above, this template was exported with Cacti 0.8.7d.
所以需要导入新版cacti模板的时候，只需要修改hash里面的version相关字段即可。
